... a square-free, or quadratfrei, integer: one divisible by no perfect square, except 1. Examples: 10 is square-free but 18 is not, as it is divisible by 9 = 32. The smallest square-free numbers: 1, 2, ...

Fractions Decimals and Percentages

... How do we know that two fractions are the same? We cannot tell whether two fractions are the same until we simplify them to their lowest terms. A fraction is in its lowest terms (simplified) if we cannot find a whole number (other than 1) that can divide into both its numerator and denominator (A c ...
