Question

How do you add `2\frac { 3} { 5}+ 5\frac { 3} { 10}`?

Answer 1

`7 9/10`

Explanation:

Find the LCM (Least Common Multiple) on the denominator. Here, the LCM is `10`. Then you have to divide `10` by `5` to change the first fraction.

`10 /5 = 2`

Next, multiply that by `3` to get `6`. Now you have the fractions

`2 6/10" "` and `" "5 3/10`

Adding that, you add the numerators and copy the denominators. Then add the whole numbers. You get

`(2+5) ((6 + 3))/10 = 7 9/10`
