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?

Question

Please I just need to know the answer and how you solved it thanks!

Answer 1

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.
