Kylie has 2 times as many cards as Anna. Anna has
38 as many cards as Wendy. If the three of them have a total of 187 cards, how many cards does Wendy have?
Kylie |
Anna |
Wendy |
2x3 |
1x3 |
|
|
3x1 |
8x1 |
6 u |
3 u |
8 u |
The number of cards that Anna has is repeated. Make the number of cards that Anna has the same. LCM of 1 and 3 is 3.
Total number of cards that the three of them have
= 6 u + 3 u + 8 u
= 17 u
17 u = 187
1 u = 187 ÷ 17 = 11
Number of cards that Wendy has
= 8 u
= 8 x 11
= 88
Answer(s): 88
