1/3+1/6=2/6+1/6=3/6=1/2
1/2*4/5=2/5
2/5+1 3/5=1 5/5=2
2:8=2/8=1/4
г
1/50+1/10=1/50+5/50=6/50=3/25
3/25:3/8=3/25*8/3=8/25
8/25-1/5=8/25-5/25=3/25
3/25*8=24/25
д
5/6-2/3=5/6-4/6=1/6
1/6*12/13=2/13
2/13+1 4/13=1 6/13
1 6/13:19=19/13*1/19=1/13

Answer 2

1/3 + 1/6 = 2/6 + 1/6 = 3/6 = 1/2
1/2 * 4/5 = 4/10 = 2/5
2/5 + 1 3/5 = 1 5/5 = 2
2 : 8 = 2/8 = 1/4 = 0,25

Г)
Делаем в обратном порядке
1/50 + 1/10 = 1/50 + 5/50 = 6/50 = 3/25
3/25 : 3/8 = 3/25 * 8/3 = 8/25
8/25 - 1/5 = 8/25 - 5/25 = 3/25
3/25 * 8 = 24/25
Д)
5/6 - 2/3 = 5/6 - 4/6 = 1/6
1/6 * 12/13 = 2/13
2/13 + 1 4/13 = 1 6/13
1 6/13 : 19 = 19/13 * 1/19 = 1/13
