`2 1/2 + 4 2/3`

The easiest way is to first add the whole numbers:

`6 + 1/2 + 2/3`

Now convert the fractions using the lowest common multiple/ denominator (LCM/ LCD). In this case that would be 6 as both 2 and 3 can be multiplied to make 6 (the first ie. lowest common multiple). :

`6+(1 times 3)/(2 times 3) + (2 times 2)/(3 times 2)`

Note how we did the same to the top as we did to the bottom

`= 6 + 3/6 + 4/6`

`= 6 7/6` Note that we have an improper fraction which must be added to the other whole number (ie the 6)

`=7 1/6`

Ans: 7  1/6

`2 1/2 + 4 2/3 `

add the 2 numbers at the front

`6 + 1/2 + 2/3 `

multiply the denominators so that they have a common multiple

`6 + (1/2 xx 3/3) + (2/3 xx 2/2) `

`6 + 3/6 + 4/6 `

add the fractions

`3/6 + 4/6 = 7/6 `

`7/6 = 1 1/6 `

add

`6 + 1 1/6= 7 1/6 `

`7 1/6`

First ignore the whole number and just add 1/2 with 2/3

1/2 and 2/3 have a common denominator of 6

By having a common denominator of 6 your equation should look like

3/6 + 4/6 now just add

By adding your fraction should look like

7/6 now we have to add the two whole numbers ( 4 and 2 )

By adding it should be

6 now include the fraction

By including the fraction it should be

= 6 7/6 since 7/6 changes to 1 1/6  your answer would be

= 7 1/6 which is your answer

first make the fractions into mixed numbers

5/2+14/3                then make a common denominator for the fractions

15/6+28/6              now add

43/6                      and simplify

7 1/6

2 1/2 + 4 2/3

5/2 + 14/3

get a common denominator or bottom number.

(15+ 28) /6 = 43/6

6 goes into 43 7 times, and you have 1 left

so 

7 1/6.
