Raeann has 4 times as many beads as Mary. Mary has
47 as many beads as Vanessa. If the three of them have a total of 108 beads, how many beads does Raeann have?
Raeann |

4x4 |
1x4 |

4x1 |
7x1 |
16 u |
4 u |
7 u |
The number of beads that Mary has is repeated. Make the number of beads that Mary has the same. LCM of 1 and 4 is 4.
Total number of beads that the three of them have
= 16 u + 4 u + 7 u
= 27 u
27 u = 108
1 u = 108 ÷ 27 = 4
Number of beads that Raeann has
= 16 u
= 16 x 4
= 64
Answer(s): 64
