Answer 3

2/3+2/5:5/4

=2/3+2/5x4/5

=2/3+8/25

=74/75

Answer 4

\(\frac{2}{3}+\frac{2}{5}\div\frac{5}{4}=\)

\(\frac{2}{5}\div\frac{5}{4}=\frac{2\times4}{5\times5}=\frac{8}{25}\)

\(\frac{2}{3}+\frac{8}{25}=\frac{50}{75}+\frac{24}{75}=\frac{74}{75}\) 

\(\frac{2}{3}+\frac{2}{5}\div\frac{5}{4}=\frac{74}{75}\)

Answer 5

= \(\frac{2}{3}+\frac{2}{5}\div\frac{5}{4}\)

= \(\frac{2}{3}+\frac{8}{25}\)

= \(\frac{74}{75}\)
