The number of passion fruit face masks at first is repeated. Make the number of passion fruit face masks the same. LCM of 3 and 5 is 15.
Total number of face masks in the end
= 4 u + 12 u
= 16 u
16 u = 176
1 u = 176 ÷ 16 = 11
Number of passion fruit masks at first
= 15 u
= 15 x 11
= 165
Answer(s): 165
