Liam works in a toy store that sells bags of marbles. he put 10 marbles in each bag and 2/10 of the marbles are striped. if Liam makes 3 bags of marbles. how many striped marbles does he need?
10 marbles in each bag...2/10 are striped...2/10(10) = 20/10 = 2 are striped.So in every bag of 10 marbles, 2 are striped. So if there is 3 bags of marbles....then (3 x 2) = 6 are striped. <== he needs 6 striped
