Tammy has 4 times as many beads as Sabrina. Sabrina has
34 as many beads as Usha. If the three of them have a total of 171 beads, how many beads does Usha have?
Tammy |
Sabrina |
Usha |
4x3 |
1x3 |

|
3x1 |
4x1 |
12 u |
3 u |
4 u |
The number of beads that Sabrina has is repeated. Make the number of beads that Sabrina has the same. LCM of 1 and 3 is 3.
Total number of beads that the three of them have
= 12 u + 3 u + 4 u
= 19 u
19 u = 171
1 u = 171 ÷ 19 = 9
Number of beads that Usha has
= 4 u
= 4 x 9
= 36
Answer(s): 36
