Answer 1

А) 1-1/3=2/3

Б) 1-3/4=1/4

В) 1-11/20=9/20

Г) 3-1/2=2+1-1/2=2+1/2= 2 целых 1/2

Д) 4-1/9=3+1-1/9=3+8/9= 3 целых 8/9

Е) 5-2/5=5+1-2/5=5+3/5= 5 целых 3/5

Ж) 6-3/7=5+1-3/7=5+4/7= 5 целых 5/7

З) 8-2/3=7+1-2/3=7+1/3= 7 целых 1/3

Answer 2

$a) 1-\frac{1}{3} =\frac{3-1}{3} =\frac{2}{3} \\\\b) 1-\frac{3}{4}= \frac{4-3}{4}= \frac{1}{4} \\\\c) 1-\frac{11}{20}= \frac{20}{11}= \frac{9}{20}\\\\d) 3-\frac{1}{2}= \frac{6-1}{2}= \frac{5}{2}=2\frac{1}{2} \\\\e) 4-\frac{1}{9}= \frac{36-1}{9}= \frac{35}{9} =3\frac{8}{9} \\\\f) 5-\frac{2}{5} =\frac{25-2}{5} =\frac{23}{5}= 4\frac{3}{5} \\\\g) 6-\frac{3}{7} =\frac{42-3}{7} =\frac{39}{7}= 5\frac{4}{7}\\\\h) 8-\frac{2}{3}= \frac{24-2}{3} =\frac{22}{3}=7 \frac{1}{3}$
