Answer 1

Answer:

$\frac{8}{10}$

Step-by-step explanation:

The missing number in the denominator would be 10, because 4 divided by 5 is 0.8, and 8 divided by 10 is also 0.8, making them congruent to one another.

You can also simplify/reduce $\frac{8}{10}$ by divided the numerator and the denominator by its common factor, 2. This gives you the fraction of $\frac{4}{5}$, proving they are equivalent to one another.

Answer 2

Answer:

10

Step-by-step explanation:

8 / x = 4/5

Multiply the second fraction by 2

4/5 *2/2

8/10

The denominator is 10
