Three-fifths x + Start Fraction 1 over 8 End Fraction Three-fifths x + Start Fraction 3 over 8 End Fraction Three-fifths x + Start Fraction 5 over 8 End Fraction Three-fifths x + Start Fraction 7 over 8 End Fraction

3/5x + 3/8

Three-fifths x + Start Fraction 3 over 8

Step-by-step explanation:

Sum of :

(2/5x + 5/8) + (1/5x - 1/4)

Open the bracket :

2/5x + 5/8 + 1/5x - 1/4

Collect like terms :

2/5x + 1/5x + 5/8 - 1/4

3/5x + (5 - 2)/8

3/5x + 3/8
