judy spent 1/2 of her saving on a bicycle and 2/5 of her saving helmet what is the total fraction of her savin that judy spent on a bicycle and a helmet
The answer is 9/10 because what I did is multiply and add. For example: 1/2 x 5/5= 5/10 and 2/5 x 2/2= 4/10 then I add this 5/10 + 4/10= 9/10 this is the answer.
