Charlie’s Math Blog Post: Adding And Subtracting Fractions

In math, we are learning how to add and subtract fractions. I think I am good at adding and subtracting fractions because it was easy to understand what you are supposed to do. Some of the problems are very easy and others are very hard.  I think it is fun because you get to figure out addition and subtraction problems.  The way it works is you take two fractions like 1/4 + 5/12 and look at the bottom number. If the two numbers are the same, you just need to add the top numbers together. But if the two numbers do not have the same denominator, you have to find the least common multiple of the two numbers. Example, 4 and 12 LCM= 12.
