Vanessa has 2 times as many coins as Fanny. Fanny has
37 as many coins as Anna. If the three of them have a total of 80 coins, how many coins does Vanessa have?
Vanessa |
Fanny |
Anna |
2x3 |
1x3 |
|
|
3x1 |
7x1 |
6 u |
3 u |
7 u |
The number of coins that Fanny has is repeated. Make the number of coins that Fanny has the same. LCM of 1 and 3 is 3.
Total number of coins that the three of them have
= 6 u + 3 u + 7 u
= 16 u
16 u = 80
1 u = 80 ÷ 16 = 5
Number of coins that Vanessa has
= 6 u
= 6 x 5
= 30
Answer(s): 30
