Morrie completed the work to solve this problem. Is his work correct?

Negative StartFraction 5 over 6 EndFraction minus (negative three-fourths) = Negative StartFraction 5 over 6 EndFraction minus three-fourths = Negative StartFraction 8 over 10 EndFraction = Negative four-fifths

What were Morrie’s errors? Check all that apply.
He should have made all the signs positive.
He should have changed Negative StartFraction 5 over 6 EndFraction minus (negative three-fourths) to Negative StartFraction 5 over 6 EndFraction + three-fourths
He should have found the common denominator, 12.
He should have subtracted StartFraction 5 over 6 EndFraction and Three-fourths
The answer should be Negative StartFraction 1 over 12 EndFraction

Error made by Morrie is B, C, E

It represents part / portion of a whole thing.

How to solve?

[tex]\frac{-5}{6} -(\frac{-3}{4}) = \frac{-5}{6} +(\frac{3}{4})[/tex]

LCM of 6 and 4 is 12

⇒ [tex]\frac{-5(2) + 3(3) }{12} = \frac{-10+9}{12} = \frac{-1}{12}[/tex]

Thus errors made by Morrie are:

B. He should have changed [tex]\frac{-5}{6} -(\frac{-3}{4}) to \frac{-5}{6} +(\frac{3}{4})[/tex]

C. He should have found the common denominator, 12.

E. The answer should be [tex]\frac{-1}{12}[/tex]
