First blank on top of 4 is x.

Second blank under 5x is 8.

Step-by-step explanation:

$\frac{3x}{8}+\frac{?}{4}=\frac{5x}{*}$

We want to find the common denominator so we can combine the fractions on the left.

The common denominator we will go for is 8 since 4(2) is 8 and 8(1)=8.

So I'm going to multiply second fraction by 2/2 giving me:

$\frac{3x}{8}+\frac{2?}{8}=\frac{5x}{*}$

Now that the denominators are the same we can write the sum as one fraction:

$\frac{3x+2?}{8}=\frac{5x}{*}$

So 3x+2?=5x if ?=x since 3+2=5.

Now *=8 so both sides can have the same denominator.

Test:

$\frac{3x}{8}+\frac{x}{4}$

Multiply second fraction by 2/2:

$\frac{3x}{8}+\frac{2x}{8}$

$\frac{3x+2x}{8}$

$\frac{5x}{8}$
