DAV Class 5 Maths Chapter 12 Worksheet 1 Notes

Fractions whose denominator is equal to hundred is called percentage.
e.g., $$\frac{52}{100}$$, $$\frac{33}{100}$$

Cent means 100. ‘Percent’ means ‘for every 100’.

By two methods a fraction can be converted into a percentage:

• By converting a fraction into an equivalent fraction with a denominator of 100.
e.g., $$\frac{7}{25}=\frac{7 \times 4}{25 \times 4}=\frac{28}{100}$$ = 28%
• By multiplying the fraction by 100.
e.g., $$\frac{7}{25}$$ = $$\frac{7}{25}$$ × 100 = $$\frac{700}{25}$$ = 28%

By two methods a decimal can be converted into a percentage:

• By converting decimals into equivalent fractions with denominator 100.
e.g., 0.4 = $$\frac{4 \times 10}{10 \times 10}=\frac{40}{100}$$ = 40%
• By multiplying decimal by 100.
e.g., 0.4 = (0.4 × 100)% = 40%

By two methods a whole number can be converted into a percentage:

• By converting whole numbers into equivalent fractions with denominator 100.
e.g., 8 = $$\frac{8 \times 100}{100}$$ = 800%
• By multiplying the whole number by 100.
e.g., 8 = (8 × 100)% = 800%
