4
7
5
8

Answer 1

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 $7$.
