Tammy has 3 times as many beads as Mary. Mary has
34 as many beads as Emily. If the three of them have a total of 48 beads, how many beads does Tammy have?
| Tammy |
Mary |
Emily |
| 3x3 |
1x3 |
|
| |
3x1 |
4x1 |
| 9 u |
3 u |
4 u |
The number of beads that Mary has is repeated. Make the number of beads that Mary has the same. LCM of 1 and 3 is 3.
Total number of beads that the three of them have
= 9 u + 3 u + 4 u
= 16 u
16 u = 48
1 u = 48 ÷ 16 = 3
Number of beads that Tammy has
= 9 u
= 9 x 3
= 27
Answer(s): 27
