This video is a simple math video showing how to add and subtract fractions using different denominators. It begins with a man explaining briefly and sitting in front of a piece of paper. He writes out a group of fractions each one with different denominators, ending in three and five. To add appropriately, on must find a common denominator, which is fifteen. So he multiplies each by five and three, raising the denominators to fifteen. This will raise the fractions to sixfifteenths and twentyfifteenths. Once added it comes out to twentysixfifteenths. Now you must divide into the fraction to make it equal. Since fifteen can go into twentysix only once you have a remainder of nine, leaving your answer which is one and ninefifteenths
