Usha, Irene, Cole and Tina shared some marbles. Usha and Irene took
16 of the total number of marbles while Cole and Tina took the rest. Irene had four times as many marbles as Usha and Tina had 64 marbles. Given that Tina had four times as many marbles as Irene, how many marbles were there altogether?

Number of marbles that Irene had is repeated. Make the number of marbles that Irene had the same. LCM of 4 and 1 is 4.
Number of marbles that Tina had = 16 u
16 u = 64
1 u = 64 ÷ 16 = 4
Total number of marbles
= 30 u
= 30 x 4
= 120
Answer(s): 120
