what is -48/9 + 4?

First we have to make these two numbers have a common demoninator. 4 can really be written as 4/1, so we get:

 

$$\frac{-48}{9} + \frac{4}{1}$$

 

Like I said, get a common demoninator by multiplying the top and bottom of the second fraction by 9.

 

$$\frac{-48}{9} + \frac{4\times9}{1\times9}$$

 

$$\frac{-48}{9} + \frac{36}{9}$$

 

Add them together:

 

$$\frac{-48 +36}{9}$$

 

$$\frac{-12}{9}$$

 

or

 

$$-1 \frac{3}{9}$$

 

which is really:

 

$$-1\frac{1}{3}$$
