Answer 2

given:

`(13)/(20) + (20)/(40)`

to find:

the sum of the two fractions.

solution:

first find the LCM of the two denominators and rename the fractions with a common denominator atlast, add and simplify.

`((13 * 40) + (20 * 20))/(20 * 40)`

`= (520 + 400)/(800)`

`= (920)/(800)`

Reduce by dividing both the numerator and denominator by the Greatest Common Factor which is 40.

`(920 / 40)/(800 / 40) = (23)/(20)`

`= 1 (3)/(20)`
