Zara, Irene, Elijah and Wendy shared some marbles. Zara and Irene took
15 of the total number of marbles while Elijah and Wendy took the rest. Irene had twice as many marbles as Zara and Wendy had 16 marbles. Given that Wendy had twice 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 2 and 1 is 2.
Number of marbles that Wendy had = 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Total number of marbles
= 15 u
= 15 x 4
= 60
Answer(s): 60
