Mulitply everything by 24 to get rid of the fractions
24(5n/6) - 24(1/4) = 24(3/8)
Simplify
4(5n) - 6 = 3(3)
20n - 6 = 9
Add 6 to each side
20n = 15
Divide both sides by 20 and reduce
n = 15/20 = 3/4
Answer: n = 3/4

Multiply both sides by 24 to get rid of the fractions:
24(5n/6-1/4)=24(3/8)
20n-6=9
Add 6 to both sides:
20n=15
Divide 20 to both sides:
n=15/20=3/4
n=3/4
Check:
20(3/4)-6=9
15-6=9
9=9
I hope that was helpful!

5n/6-1/4=3/8
(5n/6-1/4=3/8)24
= 20n - 6 = 9
=20n = 15
n = 15/20
n = 3/4

((5n)/6) - (1/4) = (3/8)
Multiply everything by 24
4(5n) - 6(1) = 3(3)
20n - 6 = 9
20n = 15
n = (15/20)
n = (3/4)
ANS : n = (3/4)

5n/6-1/4=3/8 multiply 24
20n-6=9
20n=15
n=3/4=.75

5n/6 = 3/8+2/8
5n/6 = 5/8
(5n*8)=(6*5)
40n=30
n=3/4 or .75
