Answer 1

`\begin{gathered} \text{for example, in the fist one, get you calculator and type 1/2} \\ the\text{ calculator sould show }0.5 \\ then,\text{ multiply by 100 }amd\text{ your answer is 50\%} \end{gathered}`
`\begin{gathered} for\text{ the others is similar:} \\ (3)/(20)=0.15 \\ \text{and 0.15 by 100 is 15\%} \end{gathered}`
`\text{can you try with the remaing 2 ? and let me know your questions please}`
`\begin{gathered} (1)/(5)=0.2\text{ hence 0.2 by 100 gives 20\%} \\ (1)/(10)=0.1\text{ hence 0.1 by 100 gives 10\%} \end{gathered}`
