Shannon has 3 times as many coins as Xylia. Xylia has
37 as many coins as Xuan. If the three of them have a total of 76 coins, how many coins does Shannon have?
Shannon |
Xylia |
Xuan |
3x3 |
1x3 |
|
|
3x1 |
7x1 |
9 u |
3 u |
7 u |
The number of coins that Xylia has is repeated. Make the number of coins that Xylia has the same. LCM of 1 and 3 is 3.
Total number of coins that the three of them have
= 9 u + 3 u + 7 u
= 19 u
19 u = 76
1 u = 76 ÷ 19 = 4
Number of coins that Shannon has
= 9 u
= 9 x 4
= 36
Answer(s): 36
