Comparing frisbees
and water guns at first |
1x9 =
9 u |
3x9 =
27 u |
4x9 =
36 u |
| Before |
3x3 =
9 u |
|
9x4 =
36 u |
| Change |
- 2x3 =
- 6 u |
- 182
|
- 8x4 =
- 32 u |
| After |
1x3 =
3 u |
1 u |
1x4 =
4 u |
The total number of toys at first is repeated. Make the total number of toys at first the same. LCM of 4 and 9 is 36.
The number of frisbees at first is repeated. Make the number of frisbees the same. LCM of 9 and 3 is 9.
Number of water guns left
= 4 u - 3 u
= 1 u
Number of water guns sold
= 27 u - 1 u
= 26 u
26 u = 182
1 u = 182 ÷ 26 = 7
Number of frisbees and water guns at first
= 36 u
= 36 x 7
= 252
Answer(s): 252
