Six hours ago, a grocer started his day with some kiwis and passion fruits in the ratio of 7 : 2. There were 110 passion fruits. Some of the kiwis were bought by Kimberly. As a result, the number of kiwis became
45 of the passion fruits.
- How many kiwis did the grocer have left?
- How many kiwis did the grocer have to buy in order to have an equal number of kiwis and passion fruits?

7x5 = 35 u |
2x5 = 10 u |

- ? |

After |
4x2 = 8 u |
5x2 = 10 u |
(a)
The number of passion fruits remains unchanged. Make the number of passion fruits the same. LCM of 2 and 5 is 10.
10 u = 110
1 u = 110 ÷ 10 = 11
Number of kiwis that the grocer had left
= 8 u
= 8 x 11
= 88
(b)
Number of kiwis that the grocer had to buy to have an equal number of kiwis and passion fruits
= 10 u - 8 u
= 2 u
= 2 x 11
= 22
Answer(s): (a) 88; (b) 22
