Neave and Oliver had the same number of beads. Neave gave away
57 of his beads while Oliver gave away
35 of his beads. Given that Neave gave away 12 beads more than Oliver, how many beads did Neave have at first?
| |
Neave's beads |
Oliver's beads |
| Before |
7x5 =
35 u |
5x7 =
35 u |
| Change |
- 5x5 =
- 25 u |
- 3x7 =
- 21 u |
| After |
2x5 =
10 u |
2x7 =
14 u |
The number of cards that Neave and Oliver each had at first is the same. Make the number of cards that Neave and Oliver each had at first the same. LCM of 7 and 5 is 35.
Number of beads that Neave gave away more than Oliver
= 25 u - 21 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of beads that Neave had at first
= 35 u
= 35 x 3
= 105
Answer(s): 105
