Answer 2

Ответ:

Пошаговое объяснение:

a)$\frac{10}{17}:15=\frac{10}{17}:\frac{15}{1}=\frac{10}{17}*\frac{1}{15}=\frac{10*1}{17*15}=\frac{10}{255}$

b)$\frac{9}{10}*45=\frac{9}{10}:\frac{45}{1}=\frac{9}{10}*\frac{1}{45}=\frac{9*1}{10*45}=\frac{9}{450}=\frac{1}{50}$

c)$\frac{2}{25}:5=\frac{2}{25} :\frac{5}{1}=\frac{2}{25}* \frac{1}{5}=\frac{2*1}{25*5}=\frac{2}{125}$

d)$\frac{14}{101}:7=\frac{14}{101}:\frac{7}{1}=\frac{14}{101}* \frac{1}{7}=\frac{14*1}{101*7}=\frac{14}{707}=\frac{2}{101}$

e)$\frac{8}{28}:6=\frac{8}{28}:\frac{6}{1}=\frac{8}{28}*\frac{1}{6}=\frac{8*1}{28*6}=\frac{8}{168}=\frac{1}{21}$

f)$\frac{2}{3}:60= \frac{2}{3}:\frac{60}{1}=\frac{2}{3}*\frac{1}{60}=\frac{2*1}{3*60}=\frac{2}{180}=\frac{1}{90}$

g)$\frac{15}{24}:12=\frac{15}{24} :\frac{12}{1}=\frac{15}{24} *\frac{1}{12}=\frac{15*1}{24*12}=\frac{15}{288}=\frac{5}{96}$

h)$\frac{3}{5} :12=\frac{3}{5} :\frac{12}{1}=\frac{3}{5} *\frac{1}{12}=\frac{3*1}{5*12}=\frac{3}{60}=\frac{1}{20}$

i)$\frac{14}{56} :7=\frac{14}{56} :\frac{7}{1}=\frac{14}{56} *\frac{1}{7}=\frac{14*1}{56*7}=\frac{14}{392}=\frac{1}{28}$

j)$\frac{8}{11}:32= \frac{8}{11}:\frac{32}{1}=\frac{8}{11}*\frac{1}{32}=\frac{8*1}{11*32}=\frac{8}{352}=\frac{1}{44}$

k)$\frac{32}{95} :8=\frac{32}{95} :\frac{8}{1}=\frac{32}{95} *\frac{1}{8}=\frac{32*1}{95*8}=\frac{32}{760}=\frac{4}{95}$

l)$\frac{9}{11} :42=\frac{9}{11} :\frac{42}{1} =\frac{9}{11} *\frac{1}{42}=\frac{9*1}{11*42}=\frac{9}{462}=\frac{3}{154}$
