Note that having two negatives = one positive


- (-7/4) = 7/4


Find common denominators. Multiply 3 to both numerator and denominator of 7/4


7/4(3/3) = 21/12


Combine the terms:


-9/12 + 21/12 = 12/12


Simplify:


12/12 = 1


1 is your answer

When subtracting a negative from a negative, it is like adding a positve to a negative.

-a-(-b)= -a+b

Let's find like denominators, which is 4 because 9/12 can be simplified to 3/4.

-3/4-(-7/4)= -3/4+7/4

4/4=1


So, -9/12-(-7/4)= 1
