do you know how to turn a mixed number to an improper fraction ?

Answer 2

No,sorry

Answer 3

your mixed number, -37 1/12 needs to be turned into an improper fraction. Don't worry about the negative sign right now. Anyways, take the whole number and multiply it by the denominator , then add that to the numerator, and put that over the original denominator. Thats confusing, let me show you...
(37 x 12 + 1)/12 = 445/12
do you understand how I did that ?

Answer 4

oh......and put back the negative sign....so it is - 445/12

Answer 5

now we have -51/1 + (-445/12)
are you with me so far ?

Answer 6
