\(1\frac{5}{7}\cdot\frac{3}{4}=\frac{12}{7}\cdot\frac{3}{4}=\frac{9}{7}\)
\(\frac{10}{11}:1\frac{1}{3}=\frac{10}{11}:\frac{4}{3}=\frac{15}{22}\)
\(3,57\cdot4,1+2,43\cdot4,1=(3,57+2,43)\cdot4,1\)
\(=6\cdot4,1=24,6\)

\(1\frac{5}{7}x\frac{3}{4}=\frac{12}{7}x\frac{3}{4}=\frac{9}{7}\)
\(\frac{10}{11}:1\frac{1}{3}=\frac{10}{11}:\frac{4}{3}=\frac{10}{11}x\frac{3}{4}=\frac{30}{44}=\frac{15}{22}\)
\(3,57x4,1+2,43x4,1=4,1x\left(3,57+2,43\right)=4,1x6=24,6\)
\(3,42:0,57x8,4-6,8=6x8,4-6,8=50,4-6,8=43,6\)

15/7x3/4=15x3/7x4=45/28=1 17/28(hỗn số)
10/11 : 1 1/3=10/11 : 4/3=10/11x3/4=10x3/4x11=30/44=15/22
3,57x4,1+2,43x4,1=14,637x9,963=6
