а) 7/8+1/88/8=1

б) 15/28-3/28=12/28=3/7

в) 17/23-19/23=-2/23

г) 5/21-8/21-17/21=-3/21-17/21=-20/21

д) 13/24*(-2/13)+5/12=-1/12+5/12=5/12-1/12=4/12=1/3

е) 7/9:2/3-5/6=7/9*2/3-5/6=7/6-5/6=2/6=1/3

Answer 2

a) 7/8 + 1/8 = (7+1)/8 = 8/8 = 1

b) 15/28 - 3/28 = (15-3)/28 = 12/28 = 3/7

c) 17/23 - 19/23 = (17-19)/23 = -2/23

d) 5/21 - 8/21 - 17/21 = (5-8-17)/21 = -20/21

e) 13/24 * (-2/13) + 5/12 = -1/12 + 5/12 = 4/12 = 1/3

f) 7/9 / 2/3 - 5/6 = 7/9 * 3/2 - 5/6 = 7/6 - 5/6 = 2/6 = 1/3
