Question

It takes four-eighths parts of a cloth to design a handkerchief. How much cloth is left?

• A. $0.7$
• B. $0.6$
• C. $0.4$
• D. $0.5$

Answer 1

The correct option is D $0.5$

● Let’s represent four-eighths in the numerical form.
● Four-eighths in the fraction form $=\frac{4}{8}$
● Let’s represent this fraction using a bar model.

● On observing the bar model we see that,
Part of cloth used $=\frac{4}{8}$
Part of cloth remaining $=\frac{4}{8}$
● Now, let’s represent $\frac{4}{8}$ in decimal form
● For that, we will have to make the denominator$10$ or $100.$
$\frac{4}{8}=\frac{4÷2}{8÷2}$
$\frac{2}{4}=\frac{2\times 25}{4\times 25}$
$\frac{2\times 25}{4\times 25}=\frac{50}{100}$
$\frac{50}{100}=0.5$
Hence, option A is the correct answer.
