Which number is equivalent to the expression shown below? -2 1/4 - (-8 3/8) F. -10 5/8. G. -10 1/3. H. 6 1/8. I. 6 1/2

RideAnS [48]

Change the mixed numbers into simple fractions:
-9/4-(-67/8)
Find the common denominator and subtract:
$\frac{(-9*8)-(-64*4)}{4*8} = \frac{196}{32}= \frac{49}{8} =6 \frac{1}{8}$

So your answer is H
