Answer: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
