Why do people say that dividing is the same as multiplying by the reciprocal?
Dividing by a number is the same as multiplying by its reciprocal because of the fundamental property of fractions. When you divide by a number, you can rewrite it as multiplying by one over that number. For example, dividing by 2 (or 2/1) can be expressed as multiplying by 1/2, which effectively gives the same result. This relationship simplifies calculations and is a foundational concept in arithmetic and algebra.
