Dana has 4 times as many beads as Lynn. Lynn has
47 as many beads as Diana. If the three of them have a total of 324 beads, how many beads does Diana have?
Dana |
Lynn |
Diana |
4x4 |
1x4 |
|
|
4x1 |
7x1 |
16 u |
4 u |
7 u |
The number of beads that Lynn has is repeated. Make the number of beads that Lynn 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 = 324
1 u = 324 ÷ 27 = 12
Number of beads that Diana has
= 7 u
= 7 x 12
= 84
Answer(s): 84
