Before we can evaluate a sum or difference involving mixed numbers, the mixed numbers must first be rewritten as fractions.
a bc
a* c+b/c
Simplify
-2 14
-(2* 4+1/4)
-9/4
3 14
3* 4+1/4
13/4
When adding or subtracting fractions, they should have the same denominator. We can see that this is the case.
-9/4-13/4
Now, let's perform the subtraction.
