1) 4 целых 5/6 - 2 целых 1/3 = 4 + 5/6 - 2 - 1/3= 4 + 5/6 - 2 - 2/6= 2 + 3/6= 2 + 1/2= 2 целых 1/2
2) 6 целых 3/5 - 2 целых 3/8 = 6 + 3/5 - 2 - 3/8= 6 + 3/5 - 2 - 3/8= 6 + 3/5 - 2 - 3/8= 4 + 3/5 + 5/8= 4 + 24/40 + 25/40= 4 + 49/40= 5 целых 9/40
3) 9 целых 1/2 - 4 целых 3/8 = 9 + 1/2 - 4 - 3/8= 9 + 1/2 - 4 - 3/8= 9 + 1/2 - 4 - 3/8= 5 + 1/2 + 5/8= 5 + 4/8 + 5/8= 5 + 9/8= 6 целых 1/8
1) 4 целых 5/6 - 2 целых 1/3 = 4 + 5/6 - 2 - 1/3
= 4 + 5/6 - 2 - 2/6
= 2 + 3/6
= 2 + 1/2
= 2 целых 1/2
2) 6 целых 3/5 - 2 целых 3/8 = 6 + 3/5 - 2 - 3/8
= 6 + 3/5 - 2 - 3/8
= 6 + 3/5 - 2 - 3/8
= 4 + 3/5 + 5/8
= 4 + 24/40 + 25/40
= 4 + 49/40
= 5 целых 9/40
3) 9 целых 1/2 - 4 целых 3/8 = 9 + 1/2 - 4 - 3/8
= 9 + 1/2 - 4 - 3/8
= 9 + 1/2 - 4 - 3/8
= 5 + 1/2 + 5/8
= 5 + 4/8 + 5/8
= 5 + 9/8
= 6 целых 1/8
