Erika has 2 times as many beads as Kathy. Kathy has
25 as many beads as Eva. If the three of them have a total of 44 beads, how many beads does Eva have?
| Erika |
Kathy |
Eva |
| 2x2 |
1x2 |
|
| |
2x1 |
5x1 |
| 4 u |
2 u |
5 u |
The number of beads that Kathy has is repeated. Make the number of beads that Kathy has the same. LCM of 1 and 2 is 2.
Total number of beads that the three of them have
= 4 u + 2 u + 5 u
= 11 u
11 u = 44
1 u = 44 ÷ 11 = 4
Number of beads that Eva has
= 5 u
= 5 x 4
= 20
Answer(s): 20
