Fiona has 2 times as many marbles as Vanessa. Vanessa has
34 as many marbles as Hazel. If the three of them have a total of 117 marbles, how many marbles does Hazel have?
Fiona |
Vanessa |
Hazel |
2x3 |
1x3 |
|
|
3x1 |
4x1 |
6 u |
3 u |
4 u |
The number of marbles that Vanessa has is repeated. Make the number of marbles that Vanessa has the same. LCM of 1 and 3 is 3.
Total number of marbles that the three of them have
= 6 u + 3 u + 4 u
= 13 u
13 u = 117
1 u = 117 ÷ 13 = 9
Number of marbles that Hazel has
= 4 u
= 4 x 9
= 36
Answer(s): 36
