Zoe has 2 times as many beads as Fiona. Fiona has
27 as many beads as Cathy. If the three of them have a total of 26 beads, how many beads does Zoe have?
| Zoe |
Fiona |
Cathy |
| 2x2 |
1x2 |
|
| |
2x1 |
7x1 |
| 4 u |
2 u |
7 u |
The number of beads that Fiona has is repeated. Make the number of beads that Fiona has the same. LCM of 1 and 2 is 2.
Total number of beads that the three of them have
= 4 u + 2 u + 7 u
= 13 u
13 u = 26
1 u = 26 ÷ 13 = 2
Number of beads that Zoe has
= 4 u
= 4 x 2
= 8
Answer(s): 8
