Question

a\(\frac{4}{5}\)*\(\frac{a}{b}\)=\(\frac{7}{10}\)

b\(\frac{1}{3}\):\(\frac{a}{b}\)= \(\frac{2}{3}\):\(\frac{4}{3}\) 

c\(\frac{a}{b}\)+\(\frac{3}{8}\)=\(\frac{5}{6}\)

 

Answer 1

a)=7/8

b)=2/3

c)=11/24

Answer 2

\(a,\frac{4}{5}\times\frac{a}{b}=\frac{7}{10}\)

               \(\frac{a}{b}=\frac{7}{10}:\frac{4}{5}\)

               \(\frac{a}{b}=\frac{7}{10}\times\frac{5}{4}\)

                \(\frac{a}{b}=\frac{7}{8}\)

\(b,\frac{1}{3}:\frac{a}{b}=\frac{2}{3}:\frac{4}{3}\)

    \(\frac{1}{3}:\frac{a}{b}=\frac{2}{3}\times\frac{3}{4}\)

     \(\frac{1}{3}:\frac{a}{b}=\frac{1}{2}\)

            \(\frac{a}{b}=\frac{1}{3}:\frac{1}{2}\)

            \(\frac{a}{b}=\frac{1}{3}\times2\)

             \(\frac{a}{b}=2\)

\(c,\frac{a}{b}+\frac{3}{8}=\frac{5}{6}\)

               \(\frac{a}{b}=\frac{5}{6}-\frac{3}{8}\)

                \(\frac{a}{b}=\frac{11}{24}\)

Answer 3

a)7/8

b)2/3

c)11/24
