Answer:

First blank on top of 4 is x.

Second blank under 5x is 8.

Explanation:


(3x)/(8)+(?)/(4)=(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:


(3x)/(8)+(2?)/(8)=(5x)/(*)

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


(3x+2?)/(8)=(5x)/(*)

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

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

Test:


(3x)/(8)+(x)/(4)

Multiply second fraction by 2/2:


(3x)/(8)+(2x)/(8)


(3x+2x)/(8)


(5x)/(8)
