Question

Tyrone had 97 marbles and Eric had 11 marbles. Tyrone then gave some of his marbles to Eric so that Tyrone ended with twice as many marbles as Eric. How many marbles did Tyrone give to Eric?

Answer 1

Explanation:

97 + 11 = 108 marbles in all

divide them so tyrone has 2/3 and eric has 1/3

so tyrone has 72 which means he gave away 97-72 = 25 marbles to eric
