Question

\(\frac{3}{4}\)X   \(\frac{4}{7}\)+   \(\frac{5}{14}\)

\(\frac{5}{14}\)+   \(\frac{9}{7}\):   \(\frac{3}{4}\)

\(\frac{12}{17}\):   X   =   \(\frac{3}{5}\)

Answer 1

a, \(\frac{3}{4}\times\frac{4}{7}+\frac{5}{14}\)

\(=\frac{3}{7}+\frac{5}{14}=\frac{6}{14}+\frac{5}{14}=\frac{11}{14}\)

b, \(\frac{5}{14}+\frac{9}{7}\div\frac{3}{4}\)

\(=\frac{5}{14}+\frac{9}{7}\times\frac{4}{3}=\frac{5}{14}+\frac{12}{7}=\frac{5}{14}+\frac{24}{14}=\frac{29}{14}\)

c, \(\frac{12}{17}\div x=\frac{3}{5}\)

\(x=\frac{12}{17}\div\frac{3}{5}=\frac{12}{17}\times\frac{5}{3}=\frac{20}{17}\)

Answer 2

\(\frac{3}{4}X\frac{4}{7}+\frac{5}{14}\)

\(=\frac{3}{7}+\frac{5}{14}\)

\(=\frac{6}{14}+\frac{5}{14}\)

\(=\frac{11}{14}\)

 

Answer 3

\(\frac{5}{14}+\frac{9}{7}:\frac{3}{4}\)

\(=\frac{5}{14}+\frac{9}{7}X\frac{4}{3}\)

\(=\frac{5}{14}+\frac{12}{7}\)

\(=\frac{5}{14}+\frac{24}{14}\)

\(=\frac{29}{14}\)
