Question

The ratio of frogs to toads was 3 to 7. If there were 1280 frogs and toads in all, how many were frogs?

Answer 1

348 frogs

Explanation:

ratio = 3:7

total of ratio = 10

frogs = 3/10 × 1280 = 348 frogs

Answer 2

let the ratio be 3x and 7x.

3x+7x=1280

10x=1280

x=128

Now

frogs =3x=3*128=384

toads =7x=7*128=896
