Algebra: Chapter 8 Review
Math-8, Chapter 6-4, p 289
Two numbers whose product is `1` are multiplicative inverses or RECIPROCALS of each other. So `2` and `1/2` are reciprocals.
In symbols, for a fraction `a/b`, and its reciprocal, `b/a`, the product is `(a/b)*(b/a)=1`
To divide fractions, we first change the `÷` sign into a `×` sign and then flip (or invert) the 2nd fraction. In words, to divide a fraction, multiply by its multiplicative inverses.
In symbols, for fractions `a/b` and `c/d`, `(a/b)/(c/d)=(a/b) * (d/c)`
