and kiwis at first |
7x1 =
7 u |
10x1 =
10 u |
17 u |
Before |

5x2 =
10 u |

Change |
|
- 4x2 =
- 8 u |
|
After |
7 u |
1x2 =
2 u |
45 |
The number of kiwis at first is repeated. Make the number of kiwis at first the same. LCM of 10 and 5 is 10.
Total number of fruits left
= 7 u + 2 u
= 9 u
9 u = 45
1 u = 45 ÷ 9 = 5
Number of fruits at first
= 7 u + 10 u
= 17 u
= 17 x 5
= 85
Answer(s): 85
