Question

Subtract.
7/12 from -3/28

pls give the whole solution.​

Answer 1

Answer:

Solve the equation -3/4-x=-7/12, where x is the number you're looking for. Change this to 3/4+x=7/12. This was done by multiplying the whole equation through by -1. So for now there are no minus signs. The common denominator is 3×4=12, and 3/4=9/12. Multiply 3/4 by 3/3 to get the 9/12. Now to isolate the x, subtract 9/12 from both sides of 9/12+x=7/12, remembering to add numbers to numbers and letters to letters. You get 9/12-9/12+x=7/12-9/12, x=-2/12, x=-1/6 after reducing.
