Question

Simplify the following fraction 2/5+4/6-1/3

Answer 1

11/15

Explanation:

First, get a common denominator of 30. 2/5 becomes 12/30. 4/6 becomes 20/30. 1/3 becomes 10/30.

Now we can add and subtract accordingly.

12/30 + 20/30 = 32/30.

32/30 - 10/30 = 22/30.

Finally, simplify the fraction.

22/30 becomes 11/15 when each number is divided by 2.

Answer 2

Answer:
`(11)/(15)`

Explanation:

The first step is to find the Least Common Denominator of the fractions. Descompose each denominator into its prime factors and muliply the commons and non-commons with the least exponent. Then:

`5=5\\6=2*3\\3=3\\\\LCD=2*5*3=30`

Divide each denominator by the LCD and multiply this quotient by the corresponding numerator, add the products and then reduce the fraction.

Therefore you get:

`=((2*6)+(4*5)-(1*10))/(30)=(12+20-10)/(30)=(22)/(30)=(11)/(15)`
