3/4x - 4= 1/2
add 4 to both sides
3/4x= 4 1/2
change 4 1/2 to improper fraction
3/4x= 9/2
divide both sides by 3/4
x= 9/2 ÷ 3/4
multiply by inverse of 3/4
x= 9/2 * 4/3
x= (9*4)/(2*3)
x= 36/6
x= 6

CHECK
3/4x - 4= 1/2
3/4(6) - 4= 1/2
18/4 - 4= 1/2
4 2/4 - 4= 1/2
4 1/2 - 4= 1/2
1/2= 1/2

Answer:

If the fraction is an improper fraction, the product would be higher

if the numerator of the fraction is smaller than the denominator, the product would be lower

2 x 3/4 = 3/2 = 1 1/2

2 x 4/3 = 8/3 = 2 2/3

Step-by-step explanation:

an improper fraction is a fraction in which the numerator is greater than the denominator

The numerator is the number above. While the denominator is the number below

an example of a fraction = $\frac{4}{5}$

4 is the numerator while 5 is the denominator
