1. 100

360 - 40 = 320

Pete’s marbles -> 320 / 2 = 160
Number of marbles Pete gave his brother -> 3/8 * 160 = 60
Number of marbles Pete had left -> 160 - 60 = 100

Pete had 100 marbles left.

2. 75

1/4 = 2/8

2/8 - 1/8 = 1/8

1/8 of total = 20

Adam took 20 sweets.

Barry -> 20 + 20 = 40

Total sweets -> 8 * 20 = 160

Remaining sweets -> 160 - 40 - 20 = 100

Kaden -> 1/4 * 100 = 25

Shaun 100 - 25 = 75

Shaun took 75 sweets.
