5/6 + 7/18 =

(least common multiple)LCM: 6,12,18,24,30,36

(least common multiple)LCM:18,36

I’m finding the least common multiple because then we can make the denominators the same so we can add the fractions together.

5/6 = 6×6=36 and 5×6=30 = 30/36

7/18= 18×2=36 7×2=14= 14/36

The denominators of the fractions need to be the same because the denominator represents the whole number and they both need to have the the same whole to be added together.

30/36+14/36=43/36= 1 and 7/36 

Above, I turned an improper fraction in a mixed number. This is how you do it: You minus 43 from 36 and you get 7. With the seven you have left that goes with the whole number and makes 1 and 7/36.
