Cathy has 4 times as many coins as Victoria. Victoria has
56 as many coins as Wendy. If the three of them have a total of 217 coins, how many coins does Wendy have?

4x5 |
1x5 |

|
5x1 |
6x1 |
20 u |
5 u |
6 u |
The number of coins that Victoria has is repeated. Make the number of coins that Victoria has the same. LCM of 1 and 5 is 5.
Total number of coins that the three of them have
= 20 u + 5 u + 6 u
= 31 u
31 u = 217
1 u = 217 ÷ 31 = 7
Number of coins that Wendy has
= 6 u
= 6 x 7
= 42
Answer(s): 42
