Nick had some stickers. He gave ⁵₆ of his stickers to Perry and bought 4 new stickers. After that, he gave ⁴₉ of his remaining stickers to his sister and bought another 7 new stickers. In the end, Nick had 22 stickers.

1. How many stickers did Nick give to his sister?
2. How many stickers did Nick have at first?

(a)
Fraction of  his remaining stickers after he gave to his sister
= 1 - ⁴₉
= ⁵₉

⁵₉ of his remaining stickers = 22 - 7 = 15
¹₉ of his remaining stickers = 15 ÷ 5 = 3
⁴₉ of his remaining stickers = 4 x 3 = 12

Number of stickers that Nick gave to his sister = 12

(b)
⁹₉ of his remaining stickers = 9 x 3 = 27

Fraction of his total stickers after he gave to Perry
= 1 - ⁵₆
= ¹₆

¹₆ of his total stickers = 27 - 4 = 23
⁶₆ of his total stickers = 6 x 23 = 138

Number of stickers that Nick had at first = 138 

Answer(s): (a) 12; (b) 138
