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

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

1) [latex]1 : \frac{1}{5} = \frac{1}{1} * \frac{5}{1} = \frac{5}{1} = 5[/latex] 2) [latex]1 : \frac{2}{5} = \frac{1}{1} * \frac{5}{2} = \frac{5}{2} = \frac{2*2+1}{2} = 2 \frac{1}{2} [/latex] 3) [latex]1 : \frac{22}{7} = \frac{1}{1} * \frac{7}{22} = \frac{7}{22} [/latex] 4) [latex]1 : \frac{32}{9} = \frac{1}{1} * \frac{9}{32} = \frac{9}{32} [/latex]
