Last Monday, Howard had twice as many beads as Rael. Today, Howard gives 35 of his beads to his cousin. Now, Rael has thrice as many beads as Howard. How many beads does Rael have?
| |
Howard |
Rael |
| Before |
2x3 =
6 u |
1x3 =
3 u |
| Change |
- 35 |
|
| After |
1 u |
3 u |
The number of beads that Rael had at first and in the end remains unchanged. Make the number of beads that Rael has the same. LCM of 1 and 3 is 3.
Number of beads that Howard gives to his cousin
= 6 u - 1 u
= 5 u
5 u = 35
1 u = 35 ÷ 5 = 7
Number of beads that Rael has
= 3 u
= 3 x 7
= 21
Answer(s): 21
