Answer 1

Explicación paso a paso:

5/6-1/2 = 5(2)-6(1) / 6(2) = 10-6/12 = 4/12 = 1/3

17/12-3/4 = 17(4)-12(3) / 12(4) = 68-36/48 = 32/48 = 2/3

9/10-8/5 = 9(5)-10(8) / 10(5) = 45-80/50 = - 35/50 = - 7/10

20/24-3/9 = 20(9)-24(3) / 24(9) = 180-72/216 = 108/216 = 1/2

35/40-10/8 = 35(8)-40(10) / 40(8) = 280-400/320 = - 120/320 = - 12/32 = - 3/4

18/12-21/30 = 18(30)-12(21) / 12(30) = 540-252/360 = 288/360 = 4/5
