Which number can be inserted in the parentheses so the numbers are ordered from least to greatest? negative 3, left-parenthesis space right-parenthesis, negative 1 and one-eighth a. negative 3 and one-half b. 0 c. negative 2 and one-fourth d. one and one-half

We have that
negative 3, left-parenthesis space right-parenthesis, negative 1 and one-eighth 
[-3,(  ),-1,1/8]

we know that
the number to insert must be between -3 and -1> (-3,-1)

A.negative 3 and one-half > is not in the interval (-3,-1)
B.0 > is not in the interval (-3,-1)
C.negative 2 and one-fourth > -2 1/4 belong to the interval (-3,-1) 
D.one and one-half  > is not in the interval (-3,-1)

therefore 
the answer is the option
C.negative 2 and one-fourth 

Where are the

The decimal expansion would be .27 repeated
