Question

решите пожалуйста: 1: 1/5 = , 1 : 2/5 =, 1: 22/7 =, 1: 32/9 =

Answer 1

1: 1/5 = 5
1 : 2/5 =5/2=2  1/2
1: 22/7 =7/22
1: 32/9 =9/32

Answer 2

1) $1 : frac{1}{5} = frac{1}{1} * frac{5}{1} = frac{5}{1} = 5$

2) $1 : frac{2}{5} = frac{1}{1} * frac{5}{2} = frac{5}{2} = frac{2*2+1}{2} = 2 frac{1}{2}$

3) $1 : frac{22}{7} = frac{1}{1} * frac{7}{22} = frac{7}{22}$

4) $1 : frac{32}{9} = frac{1}{1} * frac{9}{32} = frac{9}{32}$
