Answer 1

Answer: Choice C) -2 & 1/8

==============================================

Work Shown:

5 & 5/8 = 5 + 5/8

-5 & 5/8 = -(5 & 5/8) = -(5 + 5/8) = -5 - 5/8

So,

( -5 & 5/8 ) + ( 3 & 1/2 )

( -5 - 5/8 ) + ( 3 + 4/8 )

( -5+3 ) + ( -5/8+4/8 )

-2 + (-1/8)

-(2 + 1/8)

-(2 & 1/8)

-2 & 1/8

------------------------

Alternative Method

We could convert each mixed number to decimal form

-5 & 5/8 = -5-5/8 = -5.625

3 & 1/2 = 3+1/2 = 3.5

( -5 & 5/8 ) + ( 3 & 1/2 ) = -5.625+3.5 = -2.125

Then convert back to mixed number form

-2.125 = -2 & 125/1000

-2.125 = -2 & (1*125)/(8*125)

-2.125 = -2 & 1/8
