Question

find the value of n to make equivalent ratios​

Answer 1

Answer:

1.) 9/27

2.)13/27

3.)6:7

4.) 2:20

5.) 5:7

Answer 2

Answer:

1) 3:8 = 9:n

3/8 = 9/n

cross multiply:-

3n = 72

n = 72/3

n = 24

2) 4:9 = n:27

4/9 = n/27

cross multiply:-

9n = 108

n = 108/9

n = 12

3) 12:14 = n:7

12/14 = n/7

cross multiply:-

14n = 84

n = 84/14

n = 6

4) 1:10 = n:20

1/10 = n/20

cross multiply:-

10n = 20

n = 20/10

n = 2

5) 20:28 = 5:n

20/28 = 5/n

cross multiply:-

20n = 140

n = 140/20

n = 7
