Question

I have some cake. After I gave 2/5 of my cake to my sister, 180g of cake remained. how many grams of cake did I have originally?

help asap

Answer 1

300 grams. If 180 is 3/5, then 60 is 1/5. I multiplied that by 5 to get the original amount

Answer 2

x = 300

Explanation:

1 - 2/5 = 3/5

3/5 multiply x = 180

3/5 x 300 = 180

x = 300
