Answer 1

Answer:

I will solve in 2 ways...

You can use the one that you find easy

Step-by-step explanation:

given the ratios are 1:2:5

sum of the ratios = 1+2+5

= 8

percentage:-

1. 1 = 1/8×100

= 1 × 12.5

= 12.5%

2. 2 = 2/8×100

= 1/4×100

= 1 × 25

= 25%

3. 5 = 5/8×100

= 5×12.5

= 62.5%

OR

Let the ratio be x,2x,5x.

x+2x+5x=100%

=>8x=100

=>x=100/8

=>x=12.5%

Therefore,

x=12.5%

2x=25%

5x=62.5%
