Jean has 4 times as many beads as Opal. Opal has
56 as many beads as Linda. If the three of them have a total of 279 beads, how many beads does Jean have?
Jean |
Opal |
Linda |
4x5 |
1x5 |
|
|
5x1 |
6x1 |
20 u |
5 u |
6 u |
The number of beads that Opal has is repeated. Make the number of beads that Opal has the same. LCM of 1 and 5 is 5.
Total number of beads that the three of them have
= 20 u + 5 u + 6 u
= 31 u
31 u = 279
1 u = 279 ÷ 31 = 9
Number of beads that Jean has
= 20 u
= 20 x 9
= 180
Answer(s): 180
