Therefore, the answer is 209.

Question 2.
42 × 81 = ___________
Answer:
In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life. The major application we can see in multiplication tables.
In arithmetic, the multiplication of two numbers represents the repeated addition of one number with respect to another. These numbers can be whole numbers, natural numbers, integers, fractions, etc. If m is multiplied by n, then it means either m is added to itself ‘n’ number of times or vice versa.
The formula for multiplication:
The multiplication formula is given by:
Multiplier × Multiplicand = Product
– The multiplicand is the total number of objects in each group
– A multiplier is the number of equal groups
– Product is the result of multiplication of multiplier and multiplicand

Therefore, the answer is 3402.

Question 3.
821 ÷ 64 = ____________
Answer:
The meaning of divide is to separate into two or more equal parts, areas, classes, categories, groups or divisions. In simple words, the meaning of divide is to distribute the whole thing to a group in equal parts or make equal parts. The result of a division operation may or may not be an integer. Sometimes, the result will be in the form of decimal numbers.
Divide symbol:
The symbol used to represent divide or division is ÷, slash (/) or a horizontal line ( _ ). These symbols are used as per convenience while dealing with various types of problems and calculations. Also, x/y or 180 Days of Math for Fifth Grade Day 172 Answers Key q3
Division formula: The four important terms used in the division operation are dividend, divisor, quotient and remainder. The formula to calculate the division of two numbers is:
Dividend ÷ Divisor = Quotient + Remainder.
Here,
The dividend is the number, which is being divided
The divisor is the number, which divides the number (dividend) into equal parts
The quotient is the result of the division operation
The remainder is the leftover number in the division operation.

The quotient is 1208; the remainder is 18

Question 4.
Is 68,569 greater than or less than 68,659?
Answer:
68,569 is less than 68,659.
Some of the inequality symbols are less than, greater than symbol, less than or equal to, greater than or equal to, etc. If both the numbers are equal, we use an equal sign. In case, if the first number is smaller or greater than the second number, we use an inequality symbol.
The above-given numbers are 68,569, 68,659
There are two rules to compare the numbers;
1. Numbers with more digits
2. Numbers starting with a larger digit
Rule 1: When we compare numbers, then check if both the numbers are having the same number of digits or not. If a number has more digits, then it is greater than the other number.
Rule 2: This rule is applicable when two numbers are having the same number of digits. In such cases, we need to check the digit at the leftmost place, whichever is greater. Therefore, the number with a greater digit at the leftmost place of the number is greater than the other number.
Since both numbers are having an equal number of digits, therefore, we will compare the left-most digit of both numbers.
As we can see the first two digits are the same for both the numbers, thus we need to compare the next left-most digit of both numbers.
5 < 6
Therefore,
68,569 < 68,659
Hence, 68,569 is less than 68,659.

Question 5.
\(\frac{1}{10}\) × 40 = ____________
Answer:
\(\frac{1}{10}\) can be written as 1/10
Now we need to multiply by 40.
= 1/10 × 40
180 Days of Math for Fifth Grade Day 171 Answers Key q4
Therefore, \(\frac{1}{10}\) × 40 = 4.

Question 6.
Write the number that comes next in the sequence. 32,756; 32,856; 32,956;
Answer:
The above-given numbers are: 32,756; 32,856; 32,956; next number (x).
Identify the pattern of the sequence by finding the difference between two consecutive terms.
32,956 – 32,856 =100
32,856 – 32,756 = 100
The pattern of the sequence is, therefore, the addition of 100 to the preceding term.
so,
32,956 + 100 = 33,056.
Therefore, the next number (x) = 33,056.
Thus, the sequence numbers are: 32,756; 32,856; 32,956; 33,056.

Question 7.
90 ÷ 10 = 180 Days of Math for Fifth Grade Day 171 Answers Key 1 ÷ 5
Answer:
Assume that the empty box be ‘X’
90 ÷ 10 = X ÷ 5
90 ÷ 10 = 9
X ÷ 5 = 9
We need to find out the X so that both the terms should be equal.
Check out the 5th table:
we know that 5 × 9 = 45
If we put 45 in the place of X then the expression will be:
45 ÷ 5 = 9
Therefore, 9 = 9
Hence answer is verified.

Question 8.
325 cm = __________ m
Answer:
We already know that,
1 cm=0.01 m
So here asked, 325 cm ie equal to how many metres.
So what we do is multiply 325 by 0.01 metres.
325 cms = 325 × 0.01m
Therefore, 325 cm is equal to 3.25 metres

Question 9.
How many edges does a triangular pyramid have?
Answer:
Edges of the triangular pyramid:
The edges of a triangular pyramid are the line segments that join two vertices. The edges are located at the limits of the pyramid. The edges are also defined as the line segments where two triangular faces of the pyramid meet. In total, a triangular pyramid has 6 edges. In the diagram, we can see that each face has three edges and each edge is shared by two triangular faces.

180 Days of Math for Fifth Grade Day 171 Answers Key 2
Answer:
Triangle.
180 Days of Math for Fifth Grade Day 171 Answers Key q10
Definition of a triangle: A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°. It is a polygon having the least number of sides. In other words, a triangle is defined as a three-sided two-dimensional figure whose interior angles are equal to 180°.

Question 11.
You have a bag of 12 marbles. Six of the marbles are blue, two are green, three are yellow, and one is red. If you reach into the bag and grab one marble, which colour marble has about a 17% chance of being selected?
Answer:
Above-given:
The number of marbles in a bag=12
The number of blue marbles=6
The number of green marbles=2
The number of yellow marbles=3
The number of red marbles=1
In the question, if we grab one marble, which colour marble has a 17% chance of being selected.
17% is given:
percentages imply “for every hundred”.
17/100 = 0.17
Thus, 17% becomes 0.17
multiply the number of attempts by the per cent probability in decimal form. The answer will be the number of times the event should occur.
0.17 x 12 = 2.04 Which is nothing but 2.
Therefore, green marbles have the chance of being selected.

Question 12.
Fill in the grid below using the information given. Then answer the question.
180 Days of Math for Fifth Grade Day 171 Answers Key 3
One of the squares is in yellow. There is twice as much blue as yellow. The rest is orange. What percentage of the square is orange?
Answer:
180 Days of Math for Fifth Grade Day 171 Answers Key q12
Suppose, if the square is 100% then here 4 squares are there in the grid.
Then each square will be 25%.
So, the percentage of squares in orange is 25%.
