How to manually calculate math with fractions.
Addition & Subtraction:
To add or subtract, you first need a common denominator. Multiply the numerators and denominators cross-wise:(a/b) ± (c/d) = (a*d ± c*b) / (b*d)
Multiplication:
Multiply the top numbers together, and multiply the bottom numbers together:(a/b) * (c/d) = (a*c) / (b*d)
Division:
Flip the second fraction (find its reciprocal) and multiply:(a/b) ÷ (c/d) = (a/b) * (d/c) = (a*d) / (b*c)
