Question : 10

Total: 40

Express

30\%

Solution:

Concept:

Percent means “out of

100

,” so write the percentage as a fraction with denominator

100

Explanation:

Write

30\%

\frac{30}{100}

Now reduce this fraction to its lowest term.

The HCF of

30

and

100

10

Divide both numerator and denominator by

10

\frac{30 \div 10}{100 \div 10} = \frac{3}{10}

Since

3

and

10

have no common factor other than

1

\frac{3}{10}
