Anna has 3 times as many coins as Raeann. Raeann has
27 as many coins as Irene. If the three of them have a total of 135 coins, how many coins does Anna have?
Anna |
Raeann |
Irene |
3x2 |
1x2 |
|
|
2x1 |
7x1 |
6 u |
2 u |
7 u |
The number of coins that Raeann has is repeated. Make the number of coins that Raeann has the same. LCM of 1 and 2 is 2.
Total number of coins that the three of them have
= 6 u + 2 u + 7 u
= 15 u
15 u = 135
1 u = 135 ÷ 15 = 9
Number of coins that Anna has
= 6 u
= 6 x 9
= 54
Answer(s): 54
