Answer:
[tex]=77.5[/tex]
Step-by-step explanation:
[tex]\mathrm{Convert\:}155\%\mathrm{\:into\:a\:decimal\:and\:multiply\:by\:}50[/tex]
[tex]Percent-\mathrm{A\:ratio\:expressed\:as\:a\:fraction\:out\:of\:a\:hundred.}[/tex]
[tex]=155\%\:[/tex]
In order to covert a percent to a ratio, divide it by 100: a% =[tex]\frac{a}{100}[/tex]
[tex]a=155[/tex]
[tex]155\%\:=\frac{155}{100}[/tex]
[tex]\mathrm{Convert\:to\:decimal\:form}[/tex]
[tex]=1.55[/tex]
[tex]\mathrm{Multiply\:}1.55\mathrm{\:by\:}50[/tex]
[tex]=1.55\cdot \:50[/tex]
[tex]\mathrm{Simplify}\:1.55\cdot \:50[/tex]
[tex]=77.5[/tex]
