How to calculate with fractions

To add or subtract fractions, find the Least Common Denominator (LCD), convert both fractions, then combine the numerators. For multiplication, multiply numerator by numerator and denominator by denominator. For division, flip the second fraction and multiply. Simplify the answer by dividing both parts by their Greatest Common Divisor (GCD).
