Last time, I did a post about adding unlike denominators and some of my classmates commented on it. Both comments said that to explain what a least common multiple is and what a mixed number is. So I will be explaining that today!

LCM: A least common multiple is when you are skip counting with the number from your’e denominator and is when you are skip counting, you need to find the number that is the same so you can multiply your’e numerator and your’e denominator to make the denominator so you can add the fractions together.

Mixed Number: A mixed number is a fraction that has a whole and a fraction with it. For example, if I had 10/9 I would have to turn it into 1 and 1/9 to make it into a real fraction or so called mixed number.

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.
