Yen has 3 times as many beads as Nora. Nora has
56 as many beads as Penelope. If the three of them have a total of 104 beads, how many beads does Yen have?
Yen |
Nora |
Penelope |
3x5 |
1x5 |
|
|
5x1 |
6x1 |
15 u |
5 u |
6 u |
The number of beads that Nora has is repeated. Make the number of beads that Nora has the same. LCM of 1 and 5 is 5.
Total number of beads that the three of them have
= 15 u + 5 u + 6 u
= 26 u
26 u = 104
1 u = 104 ÷ 26 = 4
Number of beads that Yen has
= 15 u
= 15 x 4
= 60
Answer(s): 60
