Covert 77 1/2% to a fraction in lowest term
Elodia [21]

77\frac{1}{2} \% converted to fraction in lowest terms is \frac{31}{40}

<em><u>Solution:</u></em>

Given that we have to convert 77\frac{1}{2} \% to fraction in lowest terms

Let us first convert the mixed fraction 77\frac{1}{2}

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

Therefore,

77\frac{1}{2} \% = \frac{77 \times 2+1}{2} \% = \frac{155}{2} \%

\frac{155}{2} \% = 77.5 \%

Now convert 77.5 % to fraction

So we have to convert percentage to fraction

Divide the percentage by 100 to get a decimal number

77.5 \% = \frac{77.5}{100} = 0.775

Use that decimal number as the numerator of a fraction. Put a 1 in the denominator of the fraction

Count the number of places to the right of the decimal. If you have x decimal places then multiply numerator and denominator by 10^x

0.775 = \frac{0.775}{1} \times \frac{1000}{1000} = \frac{775}{1000}

Simplify and reduce the fraction to lowest terms

\rightarrow \frac{775}{1000} = \frac{31}{40}

Thus the given percentage is converted to fraction in lowest terms
