Passion fruits |
Mangoes |
Before |
2x7 = 14 u |
3x7 = 21 u |
Change |
No change |
- 45 |
After |
7x2 = 14 u |
3x2 = 6 u |
40% =
40100 =
25 70% =
70100 =
710 The number of passion fruits remains unchanged at first and in the end. Make the number of passion fruits the same. LCM of 7 and 2 is 14.
Number of mangoes removed
= 21 u - 6 u
= 15 u
15 u = 45
1 u = 45 ÷ 15 = 3
Number of mangoes
= 21 u
= 21 x 3
= 63
Answer(s): 63
