Answer 1

A ratio of two integers is the same as a fraction.

 

1)

 

- (3  3/4) is a mixed number.  We need to convert this into an improper fraction.

 

Multiply the whole number by the denominator and add the result to the numerator.  This will be the numerator of the new fraction.  Keep the denominator.

 

 

- 15/4

 

 

2) 

 

Do the same as question 1.

 

 

 

3)

 

-0.8 is a decimal that needs to be converted to a fraction.  We can read this number as 8 tenths.

 

-0.8 = -8/10
