Subtracting Fractions For Dummies
Subtracting Fractions For Dummies. Take the second fraction and flip it, and change the division sign to a multiplication sign, making it a reciprocal. Take the lcm of the denominator.
Converting fractions so they share the same denominator involves finding a common denominator. Subtract the results from step 1. Or, borrow 1 from the whole #, and turn that into a fraction with the same denominator as the fraction you are subtracting.
Subtract The Top Numbers (The Numerators).
Factors for 8 = 1, 2, 4, 8. 2 goes into 6 3 times, so you multiply both the numerator and denominator by 3 and get 3/6. Dummies has always stood for taking on complex concepts and making them easy to understand.
