After khalil gave benjamin 3/5 of the rocks in his collection, benjamin had 70 rocks. if benjamin had 25 rocks in the beginning, how many rocks did khalil have in the beginning?

Benjamin had 25 rocks in the beginning...70 - 25 = 45
so 3/5 of Khalil's rocks are 45 rocks...

(3/5)/45 = 1/x
cross multiply
3/5x = 45
x = 45 * 5/3
x = 225/3
x = 75 <== khalil had 75 rocks to begin with

What are the options
