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?

Answer 1

70 - 25 = 45

(3/5)x = 45

x = 45 / (3/5)

x = 45 * (5/3)

x = 225/3 = 75

Answer 2

My answer, that I got, was 225.

Answer 3

225
