Let's build a solid foundation of equal parts so that we'll be ready for fractions in third grade. From circles to rectangles, this unit will make you a whiz at identifying fractional parts.
Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole.
There are 3 Simple Steps to Divide Fractions: Step 1. Turn the second fraction (the one you want to divide by) upside down. (this is now a reciprocal). Step 2. Multiply the first fraction by that reciprocal. Step 3. Simplify the fraction (if needed) Example: 1 2 ÷ 1 6. Step 1. Turn the second fraction upside down (it becomes a reciprocal):
