Answer 1

$\left(a\right)\frac{1}{2}=\frac{1}{2}\times \frac{50}{50}=\frac{50}{100}=0.50=0.5$

$\left(b\right)\frac{1}{5}=\frac{1}{5}\times \frac{20}{20}=\frac{20}{100}=0.20=0.2$

$\left(c\right)\frac{1}{2}=\frac{1}{2}\times \frac{50}{50}=\frac{50}{100}=0.50=0.5$

$\left(d\right)\frac{5}{8}=\frac{5}{8}\times \frac{125}{125}=\frac{625}{1000}=0.625=0.625$

$\left(e\right)\frac{7}{8}=\frac{7}{8}\times \frac{125}{125}=\frac{875}{1000}=0.875=0.875$

$\left(f\right)1\frac{1}{4}=\frac{5}{4}\times \frac{25}{25}=\frac{125}{100}=1.25$

$\left(g\right)3\frac{4}{5}=\frac{19}{5}\times \frac{20}{20}=\frac{380}{100}=3.8$

$\left(h\right)5\frac{2}{5}=\frac{27}{5}\times \frac{20}{20}=\frac{540}{100}=5.4$

$\left(i\right)13\frac{13}{40}=\frac{533}{40}\times \frac{25}{25}=\frac{13,325‬}{1000}=13.325$

$\left(j\right)23\frac{3}{8}=\frac{533}{40}\times \frac{125}{125}=\frac{66,625‬}{1000}=66.625$
