12 May : April = 1 : 2
The number of pears in April is repeated. Make the number of pears in April is the same. LCM of 13 and 2 is 26.
Number of more pears in March than May
= 20 u - 13 u
= 7 u
7 u = 77
1 u = 77 ÷ 7 = 11
Number of pears that Gabriel bought in March
= 20 u
= 20 x 11
= 220
Answer(s): 220
