Question

Solve. You can leave your answer improper.(-4/5) - 7/8

Answer 1

To sum these two fractions algebraically, we can proceed as follows:

Since 67 is a prime number, then, we cannot simplify more the fraction, thus the result is:

`-(67)/(40)`

We multiply either denominator with the numerator as shown in the drawing (blue and green segments), and the two denominators to find the final answer (see that the signs remain negative while doing the operation).
