Question

type the missing number that makes these fractions equal:
\frac{\square}{4} = \frac{10}{20}

Explanation:

Step1: Let the missing number be \( x \)

We have the equation \( \frac{x}{4} = \frac{10}{20} \)

Step2: Cross - multiply

Cross - multiplying gives us \( 20x = 10\times4 \)

Step3: Simplify the right - hand side

\( 10\times4 = 40 \), so the equation becomes \( 20x = 40 \)

Step4: Solve for \( x \)

Divide both sides of the equation by 20: \( x=\frac{40}{20}=2 \)
