100% - 70% = 30%
30% =
30100 =
310 July : June = 3 : 10
The number of avocados in June is repeated. Make the number of avocados in June is the same. LCM of 13 and 10 is 130.
Number of less avocados in July than May
= 100 u - 39 u
= 61 u
61 u = 305
1 u = 305 ÷ 61 = 5
Number of avocados that Ryan bought in June
= 130 u
= 130 x 5
= 650
Answer(s): 650
