Question 2.
Solve the following questions.
(a) In a box, there are 100 chalks. Out of these 65 chalks are blue and the rest are pink in colour. Complete the following statements.
Solution:
Fraction of blue chalks = \(\frac{65}{100}\) = 65%
Number of pink chalks = 35
Fraction of pink chalks = \(\frac{35}{100}\) = 35%
(b) Anuj had 100 stamps. Out of these, 32 are foreign stamps and the rest are Indian stamps. Find the percentage of Indian stamps that Anuj had.
Solution:

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%
