## 180 Days of Math for Sixth Grade Answers Key Day 137

**Directions: Solve each problem.**

Question 1.

Answer:

Explanation:

Perform subtraction operation on above two given numbers. Subtract 68 from 362 the difference is 294.

Question 2.

3 × 40 = ___________

Answer:

3 × 40 = **120**

Explanation:

Perform multiplication operation on above two given numbers. Multiply 3 with 40 the product is 120.

Question 3.

Answer:

Explanation:

Perform division operation on above given numbers. Divide 924 by 8 the quotient is **115.5**.

Question 4.

Write the factors of 27.

Answer:

The factors of 27 are **1, 3, 9 and 27**.

Explanation:

We can write 27 as a product of two numbers in multiple ways:

27 = 1 × 27

27 = 3 × 9

The factors of 21 are 1, 3, 9, and 27.

Question 5.

Write 2\(\frac{3}{4}\) as an improper fraction.

Answer:

2 3/4 = (8 + 3)/4 = **11/4**

The improper fraction is 11/4.

Explanation:

To convert the given mixed number 2 3/4 to improper fraction, We have to follow the below steps.

First multiply the whole number 2 by the denominator 4.

2 × 4 = 8

The product 8 is added to the numerator 3.

8 + 3 = 11

Now, we have to write the answer 11 which is obtained from the above step over the denominator.

The improper fraction for 2 3/4 is 11/4.

Question 6.

18 ÷ 6 + 4^{2} – 5 = _________

Answer:

18 ÷ 6 + 4^{2} – 5

= 18 ÷ 6 + 4^{2} – 5

= 3 + 16 – 5

= 19 – 5

=** 14**

Explanation:

First perform division operation on the given expression. Divide 18 by 6 the quotient is 3. Now the expression is 3 + 4^{2} – 5.

The square of 4 is 16. The modified expression is 3 + 16 – 5.

Next perform addition operation. Add 3 with 16 the sum is 19. Now the expression is 19 -5.

Finally subtract 5 from 19 the difference is 14.

Question 7.

943 – = 425

Answer:

943 – = 425

Explanation:

By subtracting 518 from 943 then we get the difference as 425. The missing number is 518.

Question 8.

Find q.

\(\frac{q}{32}\) = 6

q = ___________

Answer:

\(\frac{q}{32}\) = 6

q = 6 × 32

**q = 192**

Explanation:

The given expression is \(\frac{q}{32}\) = 6. To calculate q value we have to perform multiplication operation on 6 and 32. Multiply 6 with 32 the product is 192.

Question 9.

How many grams are in 3.9 kilograms?

Answer:

1** kilogram (kg)** is equal to 1000** grams** (g).

3.9 kilograms

To convert kilograms into grams we need to multiply 3.8 kg with 1000 g.

= 3.9 × 1000 g

= **3,900 g**

There are 3,900 grams in 3.9 kilograms.

Question 10.

How many edges does a rectangular prism have?

Answer:

**A rectangular prism has 12 edges**. A rectangular prism has 6 faces, 4 edges.

Question 11.

What is the probability of not picking a triangle?

Answer:

In the above image we can observe 2 circles, 5 triangles, 1 square and 3 rectangles.

**2 + 5 + 1 + 3 = 11**

The total objects are 11 and out of those 11 objects 6 are not triangles.

So, the probability of not picking a triangle is **6/11**.

Question 12.

Complete the factor wheel to show all the factors of the number in the center.

Answer:

**Factors of 30: 1, 2, 3, 5, 6, 10, 15 and 30.
**The pair factors are (1, 30), (2, 15), (3, 10), (5, 6).

Explanation:

The numbers which divide a number 30 completely leaving a remainder zero are the factors of 30. In the above image we can observe the wheel is Completed with the factors to show all the factors of the number in the center. The pair factors are (1, 30), (2, 15), (3, 10), (5, 6).
