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)
