-13/6 or (in mixed number form) - 2 1/6
Step-by-step explanation:
Rewriting our equation with parts separated
=10+512-12-712
Solving the whole number parts
10-12=-2
Solving the fraction parts
512-712=-212
Reducing the fraction part, 2/12,
-212=-16
Combining the whole and fraction parts
-2-16=-216
Another way to do it:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
125/12-151/12
Applying the fractions formula for subtraction,
= (125*12) - (151*12) / 12*12
=1500 - 1812 / 144
=-312/144
Simplifying - 312/144, the answer is
=-2 1/6
