What is the distance number between two numbers 3/4 , 1/8?

Answers are 7/8 and -5/8.

Given:
Price of the house = 115,732.80
down payment = 10% of the price

115,732.80 * 10% = 11,573.28

Gross monthly salary = 2,624
expenses:
monthly = 1,150.12
sss = 2,624/2 = 1,312 * 6.2% = 81.34
medicare = 1,312 * 1.45% = 19.02
State and Federal taxes: 53 + 101.35 = 154.35
Total Monthly expenses = 1,404.83

2,624 - 1,404.83 = 1,219.17

11,573.28 / 1,219.17 = 9.5 month or 10 months.
