Question

What is 12/5 minus 2/3

Answer 1

Easy, first find a common denominator,

5: 5,10,15

3: 3,6,9,12,15

The common denominator is 15.


`(12)/(5)`
-

`(2)/(3)`

changes into


`(12)/(5)* (3)/(3)= (36)/(15)`
and

`(2)/(3)* (5)/(5) = (10)/(15)`

Now you can subtract.


`(36)/(15)- (10)/(15)= (26)/(15)`

Thus,
`(26)/(15)` or 1 11/15 is your answer.

Answer 2

= 12/5+-2/3

= 12/5+ -2/3

36/15+-10/15

36-10/15

= 26/15 or as a decimal it will be = 1.7

I hope that's help !
