Julia's frogs are 2/5 of the amount of rimma's frogs. if rimma gives 1 /2 of her frogs to julia, what will be the ratio of julia's frogs to rimma's frogs?

9:5

Step-by-step explanation:

Rimma = x

Julia = 2/5 x

Rimma gives away 1/2 of her frogs.

Now Rimma has 1/2x and Julia has 2/5x + 1/2x=4/10x +5/10x =9/10x

Ratios are fractions so put Julia's on top of Rimma's and simplify.

(9/10 x) / (1/2x)

The x's will cancel.  Invert the second fraction and multiply.

(9/10)*(2/1) = 18/10= 9/5

Ratio of Julia's frogs to Rimma's frogs is 9:5.

ANSWER

Find out the what will be the ratio of Julia's frogs to Rimma's frogs.

To proof

let us assume that the amount of Rimma's frogs = x

than the

Julia's frogs  becomes

As given

than the

Rimma's frogs becomes

Julia's frogs becomes

Than the ratio of Julia's frogs to Rimma's frogs

thus

Hence proved

the last choice
