Easy, first find a common denominator,
5: 5,10,15
3: 3,6,9,12,15
The common denominator is 15.
[tex] \frac{12}{5} [/tex]
-
[tex] \frac{2}{3} [/tex]
changes into
[tex] \frac{12}{5}* \frac{3}{3}= \frac{36}{15} [/tex]
and
[tex] \frac{2}{3}* \frac{5}{5} = \frac{10}{15} [/tex]
Now you can subtract.
[tex] \frac{36}{15}- \frac{10}{15}= \frac{26}{15} [/tex]
Thus, [tex] \frac{26}{15} [/tex] or 1 11/15 is your answer.
