Tip for Dividing Fractions
Dividing fractions involves an extra step. You must find the reciprocal of the second fraction (the one you are dividing by) and then multiply the first fraction by it. The reciprocal is found by simply inverting the fraction. For example, to calculate (1/2) ÷ (1/4), you first flip 1/4 to get 4/1. Then, you multiply: (1/2) × (4/1) = 4/2, which simplifies to 2. This method is often remembered by the phrase "invert and multiply".
To add or subtract fractions, they must share a common denominator. If they don’t, you first need to find the lowest common multiple (LCM) of the denominators. Multiplying fractions is more straightforward - you multiply the numerators together to get the new numerator, and multiply the denominators together for the new denominator.
