22 3/10 - 10 1/5= (220/10 + 3 - 101/5)= (220/10 + 3 - 202/10)= (220 + 30 - 202)/10= 48/10= 4 8/10= 4 4/5
6 11/35 - 5 6/7= (6 + 11/35 - 5 - 6/7)= (6 - 5 + 11/35 - 6/7)= (1 + 11/35 - 30/35)= (1 - 19/35)= (35/35 - 19/35)= 16/35
16 3/8 - 9 5/6= (16 + 3/8 - 9 - 5/6)= (16 - 9 + 3/8 - 5/6)= (7 + 3/8 - 40/8)= (7 + 3/8 - 5)= (7 + 3/8 - 40/8)= (7 + 3 - 40)/8= (-30/8)= -3 6/8= -3 3/4
Итак, результаты вычитания:
22 3/10 - 10 1/5
= (220/10 + 3 - 101/5)
= (220/10 + 3 - 202/10)
= (220 + 30 - 202)/10
= 48/10
= 4 8/10
= 4 4/5
6 11/35 - 5 6/7
= (6 + 11/35 - 5 - 6/7)
= (6 - 5 + 11/35 - 6/7)
= (1 + 11/35 - 30/35)
= (1 - 19/35)
= (35/35 - 19/35)
= 16/35
16 3/8 - 9 5/6
= (16 + 3/8 - 9 - 5/6)
= (16 - 9 + 3/8 - 5/6)
= (7 + 3/8 - 40/8)
= (7 + 3/8 - 5)
= (7 + 3/8 - 40/8)
= (7 + 3 - 40)/8
= (-30/8)
= -3 6/8
= -3 3/4
Итак, результаты вычитания:
22 3/10 - 10 1/5 = 4 4/56 11/35 - 5 6/7 = 16/3516 3/8 - 9 5/6 = -3 3/4
