Greetings, maths enthusiast! Ready to journey through the magical realm of subtracting fractions? Buckle up! Just remember, fractions are like pies, they’re better when shared.
Formula: To subtract fractions, you first find a common denominator. Then, simply subtract the numerators. So, if we have a/b - c/d, it transforms into (a*d - b*c) / (b*d).
