Question

How to add/Subtract fractions With an Example and explain good

Answer 1

The first example is adding fractions. The last is Subtraction.

Explanation:

The first step is finding the LCD or Least Common Denominator. In this case, we multiply both denominators by each other 2 x 3 = 6 before we proceed.

Secondly, we multiply the bottom denominator on the right (which is three) and multiply it by numerator and denominator on the left.

`(1)/(2)` x 3= Multiply the numerator and denominator and you should get this

`(3)/(6)`

Next multiply
`(1)/(3)` by 2. You should get
`(2)/(6)`

The final step is just to add the numbers on the very top. You should get
`(5)/(6)`

*Also note, pay attention to your question. Some may require decimal form or simplification.

1.
`(1)/(2) + (1)/(3) = (5)/(6)`

2.
`(3)/(6)` +
`(2)/(6)` =
`(5)/(6)`

3. The answer is
`(5)/(6)`

_________________________________________

The next example is subtraction.

Find the LCD.

Next, start by multiplying
`(3)/(5)` by 3. Penultimately, multiply
`(1)/(3)` by 5. Finally, subtract 9-5 to get 4. The answer should be
`(4)/(15)`

1.
`(3)/(5) - (1)/(3)`

2.
`(9)/(15)` -
`(5)/(15)` =
`(4)/(15)`
