Divide Rational Fractions Worksheets

How to Divide Rational Fractions - A rational number is a number that can be written as a normal fraction, like a ratio. For example: 5 = 5/1 | 1.75 = 7/4 | .001 = 1/1000 | 0.111… = 1/9. So, a rational number looks like: P/Q. But remember, Q cannot be zero. Multiplication - So, if you are looking to multiply rational numbers, the first tip to do it successfully is multiplying the tops and bottoms with each other separately. Like this: a/b x c/d = ac / bd
1/2 x 2/5 = (1 x 2) / (2x5) = 2/10 = 1/5. Division - When it comes down to dividing the rational numbers. First, you need to flip the second number or make it a reciprocal and then multiply like below: A/B ÷ C/D or A/B x D/C = AD/BC. 1/2 divided by 1/6. Reciprocal of the second fraction = 6/1. Hence, 1/2 x 6/1 = (1 x 2) / (6x1) = 6/2 = 3. Often times student uses some pictorial or visual aid that can help them understanding the problem much better.
