Type the missing number that makes these fractions equal: 1/2 = _/20

1 answer

To find the missing number that makes the fractions equal, we can set up the equation:

\[ \frac{1}{2} = \frac{x}{20} \]

To solve for \(x\), we can cross-multiply:

\[ 1 \cdot 20 = 2 \cdot x \]

This simplifies to:

\[ 20 = 2x \]

Now, divide both sides by 2:

\[ x = \frac{20}{2} = 10 \]

So, the missing number is:

\[ \boxed{10} \]
