80% =
80100 =
45 Carl's stickers : Will's stickers = 28 : 35
Jenson's stickers: Carl's stickers = 25 : 28 (a)
Will's stickers + Carl's stickers = 35 u + 28 u = 63 u
Jenson's stickers = 25 u
63 u - 25 u = 380
38 u = 380
1 u = 380 ÷ 38 = 10
Number of Will's stickers
= 35 u
= 35 x 10
= 350 (b)
Answers: (a) 25 : 28; (b) 350
