Question

You have 10/4 kg of sugar. If you use 7/4 kg of sugar, what amount of sugar will be left?

• A. 0.75 kg
• B. 0.50 kg
• C. 1.25 kg
• D. 0.25 kg

Answer 1

The correct option is A 0.75 kg

The amount of sugar available = $\frac{10}{4}$ kg

You have used $\frac{7}{4}$ kg of sugar.

In the given number line, each segment is divided into 4 parts. Each part is equivalent to $\frac{1}{4}$

$\frac{10}{4}$ can be written as $2\frac{2}{4}$

Represent $2\frac{2}{4}$ on the number line.

To represent subtraction, move $\frac{7}{4}$ units to the left.

This reaches $\frac{3}{4}$ on the number line.
Hence, the quantity of sugar left = $\frac{3}{4}$ kg or 0.75 kg
