Jean had flying saucers for sale. In the morning, she sold ²₇ of the flying saucers. In the afternoon, she sold ²₅ of the remaining flying saucers. After that, there were 48 flying saucers left. How many flying saucers did Jean have at first?
Fraction of flying saucers left after selling in the morning
= 1 - ²₇
= ⁵₇

Fraction of the remaining flying saucers after selling in the afternoon
= 1 - ²₅
= ³₅

³₅ of remaining flying saucers = 48
¹₅ of remaining flying saucers = 48 ÷ 3 = 16
⁵₅ of remaining flying saucers = 5 x 16 = 80

⁵₇ of total flying saucers = 80
²₇ of the total flying saucers = 80 ÷ 5 = 16
⁷₇ of the total flying saucers = 7 x 16 = 112

Number of flying saucers at first = 112

Answer(s): 112
