Answer 1

Step-by-step explanation:

to convert in percent,

For example ratio is given like m:n

so we divide m by n and multiply it by 100

1. 1:5 = 1/5 * 100

        = 100/5 = 20%

2. 20:25 = 20/25 * 100

              =2000/25 = 80%

Rest u can do with same method

Hope it was helpful :)

Answer 2

a) 1 : 5 = 20%

b) 2 : 3 = 60%

c) 25 : 75 = 30%

d) 20 : 25 = 80%

e) 11 : 125 = 8.8%

f) 7 : 5 = 140%

Step-by-step explanation:

How to express ratios as a percent

• To express ratios as a percent first divide the numerator by the denominator.

• Multiply it bu 100.

• The number get will be a percent.

• Add percent symbol after a number.

___________________________

a) 1 : 5

= 1 / 5 × 100

= 0.2 × 100

= 20

= 20%

1 : 5 = 20%

___________________________

b) 2 : 3

= 2 / 3 × 100

= 0.6 × 100

= 60

= 60%

2 : 3 = 60%

___________________________

c) 25 : 75

= 25 / 75 × 100

= 0.3 × 100

= 30

= 30%

25 : 75 = 30%

___________________________

d) 20 : 25

= 20 / 25 × 100

= 0.8 × 100

= 80

= 80%

20 : 25 = 80%

___________________________

e) 11 : 125

= 11 / 125 × 100

= 0.08 × 100

= 8.8

= 8.8%

11 : 125 = 8.8%

___________________________

f) 7 : 5

= 7 / 5 × 100

= 1.4 × 100

= 140

= 140%

7 : 5 = 140%
