Question

Fill each blank that make correct number that will make equivalent ratios.
1. —:7 =24 : 56 2. 8:3= — : 15
35 : — = 20 : 8 4 : 16 = — : 8 5. 20 : 12 = 15 : —

Answer 1

Answer:

1. 3 : 7

2. 15 : 40

3. 35 : 14

4. 2 : 8

5. 15 : 9

Answer 2

Given,

1) —:7 =24 : 56

2) 8:3= — : 15

3) 5 : — = 20 : 8

4) 4 : 16 = _ : 8

5) 20: 12 = 1: —

To find,

The equivalent ratios.

Solution,

The equivalent ratios will be 1) 3:7 =24 : 56

:7 =24 : 562) 8:3= 40 : 15

: 153) 5:2 = 20 : 8

= 20 : 8 4) 4 : 16 = 2 : 8

: 85) 20: 12 = 15: 9

We can easily solve this problem by following the given steps.

To find the equivalent ratios we will divide the number in the second ratio by the first ratio in the complete pairs.

In question 1), the complete pair is the second one.

Dividing 56 by 7, we get 8.

Now, to find the equivalent ratio divide 24 by 8.

24/8 = 3

So, it is 3:7.

In question 2), the complete pair is the second one.

Dividing 15 by 3, we get 5.

Now, to find the equivalent ratio multiply 8 by 5.

8×5 = 40

So, it is 40:15.

In question 3), the complete pair is the first one.

Dividing 20 by 5, we get 4.

Now, to find the equivalent ratio divide 8 by 4.

8/4 = 2

So, it is 5:2.

In question 4), the complete pair is the second one.

Dividing 8 by 16, we get 1/2.

Now, to find the equivalent ratio we will multiply 4 by 1/2.

4×1/2 = 2

So, it is 2:8.

In question 5), the complete pair is the first one.

Dividing 15/20, we get 3/4.

Now, to find the equivalent ratio we will multiply 12 by 3/4.

12×3/4 = 9

So, it is 15:9.

(Note to find the number on the right-hand side we will divide and find on the left-hand side we will multiply.)

Hence, the equivalent ratios are 1) 3:7 =24 : 56

) 3:7 =24 : 562) 8:3= 40 : 15

) 3:7 =24 : 562) 8:3= 40 : 153) 5:2 = 20 : 8

) 3:7 =24 : 562) 8:3= 40 : 153) 5:2 = 20 : 8 4) 4 : 16 = 2 : 8

) 3:7 =24 : 562) 8:3= 40 : 153) 5:2 = 20 : 8 4) 4 : 16 = 2 : 85) 20: 12 = 15: 9
