Wesley gave ¹₈ of his stamps to Rael, ²₇ of his remaining stamps to Bryan and ¹₃ of the rest of his stamps to Jack. He then had 110 stamps left. How many stamps had he at first?
Fraction of the rest of the stamps that Wesley had left after giving to Rael, Bryan and Jack
= 1 - ¹₃
= ²₃

²₃ of the rest of the stamps that Wesley had left = 110
¹₃ of the rest of the stamps that Wesley had left = 110 ÷ 2 = 55
³₃ of the rest of the stamps that Wesley had left = 3 x 55 = 165

Fraction of his remaining stamps that Wesley had left after giving to Rael and Bryan
= 1 - ²₇
= ⁵₇

⁵₇ of his remaining stamps that Wesley had left = 165
¹₇ of his remaining stamps that Wesley had left = 165 ÷ 5 = 33
⁷₇ of his remaining stamps that Wesley had left = 7 x 33 = 231

Fraction of his remaining stamps that Wesley had left after giving to Rael
= 1 - ¹₈
= ⁷₈

⁷₈ of the stamps that Wesley had left = 231
¹₈ of the stamps that Wesley had left = 231 ÷ 7 = 33
⁸₈ of the stamps that Wesley had left = 8 x 33 = 264

Number of stamps that Wesley had at first = 264

Answer(s): 264
