Passion fruits |
Persimmons |
Before |
3x1 = 3 u |
1x1 = 1 u |
Change |
No change |
+ 40 |
After |
1x3 = 3 u |
3x3 = 9 u |
75% =
75100 =
34 25% =
25100 =
14 The number of passion fruits remains unchanged at first and in the end. Make the number of passion fruits the same. LCM of 3 and 1 is 3.
Number of persimmons added
= 9 u - 1 u
= 8 u
8 u = 40
1 u = 40 ÷ 8 = 5
Number of passion fruits
= 3 u
= 3 x 5
= 15
Answer(s): 15
