Gabriel had some stickers. He gave ²₃ of his stickers to Eric and bought 4 new stickers. After that, he gave ²₅ of his remaining stickers to his cousin and bought another 7 new stickers. In the end, Gabriel had 49 stickers.

1. How many stickers did Gabriel give to his cousin?
2. How many stickers did Gabriel have at first?

(a)
Fraction of  his remaining stickers after he gave to his cousin
= 1 - ²₅
= ³₅

³₅ of his remaining stickers = 49 - 7 = 42
¹₅ of his remaining stickers = 42 ÷ 3 = 14
²₅ of his remaining stickers = 2 x 14 = 28

Number of stickers that Gabriel gave to his cousin = 28

(b)
⁵₅ of his remaining stickers = 5 x 14 = 70

Fraction of his total stickers after he gave to Eric
= 1 - ²₃
= ¹₃

¹₃ of his total stickers = 70 - 4 = 66
³₃ of his total stickers = 3 x 66 = 198

Number of stickers that Gabriel had at first = 198 

Answer(s): (a) 28; (b) 198
