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

$5 \frac{13}{15} -1 \frac{2}{3}$

First we write them in improper fraction. That is

$= \frac{5*15+13}{15} - \frac{1*3+2}{3}$

$= \frac{88}{15} - \frac{5}{3}$

And the LCD is 15 here.

$\frac{88-25}{15} = \frac{63}{15}$

Which can be reduced to

$= \frac{21}{5} = 4 \frac{1}{5}$
