The remainder is the value left after the division. If a number (dividend) is not completely divisible by another number (divisor) then we are left with a value once the division is done. This value is called the remainder.
Remainder formula:
We know that,
Dividend = Divisor x Quotient + Remainder
Therefore,
Remainder = Dividend – (Divisor x Quotient)
This is the formula for the remainder.

X = 27
Therefore, the cost of each ticket is $27. Question 14. What is the whole-number quotient and remainder? 7,810 ÷ 215 A. 36 R33 B. 36 R70 C. 36 R79 D. 36 R170 Answer: Option B is correct. The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken. For example, 6 ÷ 2 = 3. This can be written as a multiplication fact as 2 × 3 = 6. Question 15. Which is a reasonable estimate for 89,877 ÷ 31? A. 30 B. 300 C. 3,000 D. 30,000 Answer: Option C is correct The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken. For example, 6 ÷ 2 = 3. This can be written as a multiplication fact as 2 × 3 = 6. We can verify the answer: Now take the division in this problem. According to the division algorithm, the formula is: Dividend = (Divisor × Quotient) + Remainder – The above formula helps us to verify the values of quotient and remainder obtained after performing division. We can substitute the values of the quotient, remainder, and divisor in the above equation and check whether the result is the same as the dividend or not. If we get the dividend, it means we have done the steps of division correctly. If not, it means there is an error in our calculations that we need to rectify. 90000 = ( 30 x 3000) + 0 90000 = 90000 + 0 90000 = 90000 Hence verified Spiral Review Question 16. Bea withdraws$25 from her bank account. What integer represents the withdrawal?
____________________
The amount Bea withdrew from her bank account = \$25
It represents -25 because Bea is withdrawing the money so it gets ‘-‘.

Question 17.
Which two points on the number line represent a number and its absolute value?

____________________
The absolute value of a number can be thought of as the distance of that number from 0. As distance can never be negative hence, the absolute value of a number is always positive.
According to the formula,
|x| = x, if x > 0 (x is positive)
The absolute value of |10| = 10
According to the formula,
|x| = -x, if x < 0 (x is negative)
|-10| = 10
Hence, the absolute value of -10 is 10.
The line O represents the number 2
The absolute value of |O| = O
|2| = 2
the absolute value of |P| = 6
The absolute value of |Q| = 8
The absolute value of |N| = |-3| = 3
The absolute value of |M| = |-6| = 6

Question 18.
Naruto practices his harmonica $$\frac{1}{4}$$ hour, spends $$\frac{2}{3}$$ hour working on homework, and takes another $$\frac{1}{2}$$ hour to do chores every day. How much longer does Naruto spend practising his harmonica and doing his chores than working on homework?
____________________
The time Naruto practices his harmonica = 1/4
The time he spends on homework = 2/3
The time he spends on chores = 1/2
We need to find out the more time he spends practising and doing his chores than working on homework. Let it be X.
Now add the time he spent practising and doing chores. Let it be Y.
Y = 1/4 + 1/2

Now we should find out X.
X = Y – time spent on homework
X = 3/4 – 2/3

Therefore, 1/12 times more he spends on practising and doing chores than homework.
