The number of passion fruit face masks at first is repeated. Make the number of passion fruit face masks the same. LCM of 5 and 3 is 15.
Total number of face masks in the end
= 2 u + 10 u
= 12 u
12 u = 120
1 u = 120 ÷ 12 = 10
Number of passion fruit masks at first
= 15 u
= 15 x 10
= 150
Answer(s): 150
