Given:
[tex]1\frac{3}{4}[/tex]The decimal number is:
[tex]\begin{gathered} \frac{3}{4}=0.75 \\ 1\frac{3}{4}=1+0.75=1.75 \end{gathered}[/tex]To turn this to percent, we know that:
1 = 100%
and
[tex]\frac{3}{4}=0.75*100=75[/tex]3/4 = 75%
Therefore:
[tex]1\frac{3}{4}=(1+0.75)*100=100+75=175[/tex]The answer is: 175%.
