Answer:
The answer is 5/7
Step-by-step explanation:
Let the numerator of the original fraction bee x.
By question, denominator = 2 * x - 3
the original fraction = x / 2x - 3
1/2 is subtracted from the numerator = (x - 1/2) / 2x - 3
3/5 is added to the denominator = (x - 1/2) / 2x - 3 + (3/5)
new fraction = 45/76
∴ (x - 1/2) / (2x - 3 + 2/5) = 45/76 [ lcm is 5]
= (x - 1/2) / (2x - 12/5) = 45/76 [ cross multiplication ]
76(x - 1/2) = 45 (2x - 12/5)
76x - 38 = 90x -108 [ 76x is taken to the right side of the equal to sign and and -108 to the left sign of the equal to sign]
108 - 38 = 90x - 76x
70 = 14x
x = 70/14
x = 5
∴ The numerator = 5
The denominator = 2x - 3
= 2 * 5 - 3
= 10 - 3
= 7
∴The original fraction is 5/7
