5 1/4 plus negative 2 2/3

Question

Five and ohe fourth plus negative two and two thirds

 

Answer 1

First, turn the mixed numbers into improper fractions.

 

5 1/4 = 21 / 4

 

2 2/3 = 8 / 3

 

 

Now we can perform the operations.  Plus negative is the same as subtracting.

 

(21 / 4) - (8 / 3)

 

 

We cannot subtract fractions with uncommon denominators.  We need to use the LCD.  LCD is 12.

 

(63 / 12) - (32 / 12) =

 

31 / 12
