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?

the ratio of Julia’s frogs to Rimma’s frogs is 1.8 : 1

Step-by-step explanation:

Let x represent the total number of frogs that Rimma had.

Julia’s frogs are 2/5 of the amount of Rimma’s frogs. This means that the number of frogs that Julia had is

2/5 × x = 2x/5

If Rimma gives 1/2 of her frogs to Julia, the number of frogs that Julia gets from Rimma would be

1/2 × x = x/2 frogs. Total number of frogs that Julia would have becomes

2x/5 + x/2 = (4x + 5x)/10 = 9x/0

The number of frogs that Rimma has left would be 1/2 × x = x/2

The ratio of Julia’s frogs to Rimma’s frogs would be

(9x/10) / (x/2) = (9/5)/1

= 1.8 : 1
