Question

Вычислите: 11/48-5/36; 4/5-2/3+4/15; 7/8+11/12-5/6

Answer 1

1)11/48-5/36=33/144-20/144=13/144
2)4/5-2/3+4/15=2/15+4/15=2/5
4/5-2/3=12/15-10/15=2/15
2/15+4/15=6/15=2/5
3)7/8+11/12-5/6=1 19/24-5/6=23/24
7/8+11/12=21/24+22/24=43/24=1 19/24
1 19/24-5/6=43/24-5/6=43/24-20/24=23/24

Answer 2

1. (33-20)/144=13/144
2. (12-10+4)/15=6/15=2/5
3. (21+22-20)/24=23/24
