65March : February = 6 : 5
100% - 75% = 25%
25% =
25100 =
14 April : March = 1 : 4
The number of grapefruits in March is repeated. Make the number of grapefruits in March is the same. LCM of 6 and 4 is 12.
Number of less grapefruits in April than February
= 10 u - 3 u
= 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Number of grapefruits that Perry bought in March
= 12 u
= 12 x 12
= 144
Answer(s): 144
