Answer 1

2,5 X (8/15 : 4 + 0,15)-5/24 = 2,5 * (8/15 * 1/4 + 0,15) - 5/24 = 2,5 * (2/15 + 15/100) - 5/24 = 2,5 * (2/15 + 3/20) - 5/24 = 2,5 * (8/60 + 9/60) - 5/24 = 25/10 * 17/60 - 5/24 = 17/24 - 5/24 = 12/24 = 1/2

Answer 2

2,5 x (8/15 : 3 + 0,15) - 5/24 = 8/15 x 1/4 = 8/60 = 2/15

0,15 = 15/100

2/15 + 15/100 = 40/300 + 45/300 = 85/300 = 17/60

2,5 x 17/60 = 2 i 30/60 x 17/60 = 150/60 x 17/60 = 17/24

17/24 - 5/24 = 12/24 = 1/2
