Question

How much should be subtracted from 7/4 to make it equal to positive difference of 13/5 and 9/5?

Answer 1

Answer:

5/24. You can answer this most efficiently by composing a simple linear equation.

-7/8 - x = -13/12

Add (-7/8) to each side and then multiply both sides by -1 (to clear the negative sign on x) and you get:

x = 5/24.

You can check this by computing (-7/8) - (5/24). When adding/subtracting fractions, the denominators must be equal. Multiply (-7/8) by (3/3) to get (-21/24). Subtract (5/24) and you are left with (-26/24), which can be simplified to -13/12.
