Including fractions can appear daunting at first, however with just a little follow, it is a ability that anybody can grasp. On this beginner-friendly information, we’ll stroll you thru the steps concerned in including fractions, so you’ll be able to deal with math issues with confidence.
Earlier than we dive into the steps, let’s shortly evaluation the fundamentals of fractions. A fraction represents part of a complete, and it consists of two numbers: the numerator and the denominator. The numerator is the quantity above the road (or to the left of the slash), and the denominator is the quantity under the road (or to the proper of the slash). For instance, within the fraction 3/4, 3 is the numerator and 4 is the denominator.
Now that we’ve got a primary understanding of fractions, let’s transfer on to the steps for including them.
