Question

пожалуйста помогите!!!!!​

Answer 1

1) $1\frac{7}{8}*2\frac{1}{3}=\frac{15}{8} *\frac{7}{3}=\frac{15*7}{8*3}=\frac{35}{8}=4\frac{3}{8}$

2) $3\frac{1}{7}*1\frac{3}{11}=\frac{22}{7}*\frac{14}{11}=\frac{22*14}{7*11}=4$

3) $4\frac{1}{5}*2\frac{1}{7}=\frac{21}{5}*\frac{15}{7}=\frac{21*15}{5*7}=9$

4) $6\frac{5}{7} *1\frac{2}{47} =\frac{47}{7}*\frac{49}{47}=\frac{47*49}{7*47}=7$

5) $4\frac{4}{17} *3\frac{1}{18}=\frac{72}{17}*\frac{55}{18}=\frac{4*55}{17}=\frac{220}{17}=12\frac{16}{17}$

6)$2\frac{22}{25}*1\frac{11}{24} =\frac{72}{25}*\frac{35}{24}=\frac{72*35}{25*24}=\frac{21}{5}=4\frac{1}{5}$

7) $1\frac{8}{9}*2\frac{2}{3}* \frac{3}{8} =\frac{17}{9}*\frac{8}{3}*\frac{3}{8}=\frac{17}{9}=1\frac{8}{9}$

8) $1\frac{7}{8}*3\frac{1}{5}*2\frac{1}{3}=\frac{15}{8}*\frac{16}{5}*\frac{8}{3}=\frac{15*16*8}{8*5*3}=16$
