Answer:
-7 1/4
Step-by-step explanation:
- 5 1/2 - 1.75
We need to get both numbers as fractions
-5 1/2 - 1 75/100
This simplifies to
- 5 1/2 - 1 3/4
We need to get a common denominator for the fractions, which is 4.
1/2 *2/2 = 2/4 so we can replace 1/2 with 2/4
-5 2/4 - 1 3/4
Since the signs are the same, we add and then use the negative sign.
-( 5 2/4 + 1 3/4)
- ( 6 5/4)
Changing the improper fraction to a mixed number
-( 6 + 1 1/4)
-( 7 1/4)
