Answer:
X = 4
Step-by-step explanation:
First off,
Replace all of the X with 4 so,
1/4 + 3/4 + 5/4 + 7/4 = 4.
2nd,
Put the fractions into decimals
1/4 = .25
3/4 = .75
5/4 = 1.25
7/4 = 1.75
3rd
add all of the decimals up
.25 + .75 + 1.25 + 1.75
.25 + .75 = 1
1 + 1.25 = 2.25
2.25 + 1.75 = 4.
So X = 4.
