type the missing number that makes these fractions equal:

Question

2/5 = _/10

Answer 1

To find the missing number that makes the fractions equal, you need to set up the equation:

\[ \frac{2}{5} = \frac{x}{10} \]

Cross-multiplying gives:

\[ 2 \cdot 10 = 5 \cdot x \]

This simplifies to:

\[ 20 = 5x \]

Now, divide both sides by 5:

\[ x = \frac{20}{5} = 4 \]

So, the missing number is 4.
