express 28 100 and 45:100 as percent​

Sagot :

PERCENT

==============================

» Convert the ratio in colon form into a fraction.

[tex] \implies \sf \Large \red{28 \: : \: 100}= \red{ \frac{28}{100} }[/tex]

[tex]\implies \sf \Large \blue{45 \: : \: 100}= \blue{ \frac{45}{100} }[/tex]

» Multiply it to 100

[tex] \implies \sf \Large \red{ \frac{28}{100} } \times 100 = \red{28}[/tex]

[tex]\implies \sf \Large \blue{ \frac{45}{100} } \times 100 = \blue{45}[/tex]

» Add percent sign (%)

[tex] \huge \begin{array}{l}» \: \tt \red{28\%} \\ » \: \tt \blue{45\%}\end{array}[/tex]
