Question

Find the missing number using the given model.

• A. 5
• B. 4
• C. 2
• D. 10

Answer 1

The correct option is A 5

The given model is shaded for $\frac{1}{2}$.

The shaded part ($\frac{1}{2}$) is divided into 5 equal parts.

Since we divided the shaded part into 5 equal parts, each part represents,
$\frac{1}{2}÷\frac{1}{5}=\frac{1}{10}$

Hence, the missing number is 5.
