Question

use the lowest common denominator to subtract the following fractions. Give the final answer in simplest terms. 5 13/15 - 1 2/3=

Answer 1

The given expression is

`5 (13)/(15) -1 (2)/(3)`

First we write them in improper fraction. That is

`= (5*15+13)/(15) - (1*3+2)/(3)`

`= (88)/(15) - (5)/(3)`

And the LCD is 15 here.

`(88-25)/(15) = (63)/(15)`

Which can be reduced to

`= (21)/(5) = 4 (1)/(5)`
