Question

During Diwali, 75 of the 625 letters collected from a postbox were greeting cards. What percentage of the letters were greeting cards?

Answer 1

Total number of cards = 625
Number of greeting cards = 75
We have:
$\frac{75}{625}=\frac{3}{25}$

To find the percentage of the greeting cards, we will use the fraction with denominator 100.
We will multiply the numerator and denominator by 4.
∴ $\frac{75}{625}=\frac{3}{25}=\frac{3\times 4}{25\times 4}=\frac{12}{100}$ = 12

Thus, there were 12% of the greeting cards.
