1 answer

To find the missing value in the equivalent fraction \( \frac{5}{?} = \frac{20}{28} \), we can cross-multiply:

\[ 5 \cdot 28 = ? \cdot 20 \]

Calculating \( 5 \cdot 28 \):

\[ 5 \cdot 28 = 140 \]

Now, our equation is:

\[ 140 = ? \cdot 20 \]

To find the missing value, divide both sides by 20:

\[ ? = \frac{140}{20} \]

Calculating \( \frac{140}{20} \):

\[ ? = 7 \]

Thus, the missing value is \( 7 \).

So, the answer is \( 7 \).
