If a fraction's numerator and denominator have no factors other than one in common, the fraction cannot be simplified except if the denominator is 1, in which case the fraction can be simplified to the whole number of the numerator.

The simplification will be positive. In other words, the numerator and the denominator will NOT stay negative.

Multiply the numerator and the denominator by the same integer.

irreducible fraction An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered).

Multiply the numerator of one fraction to the other then multiply the denominator of one fraction to the other . Then reduce if possible.

"The numerator and denominator are known as the fraction bar.”

taking two fractions. and cross multiply. all fraction has a numerator (top number) and a denominator (bottom number). multiply the numerator to the other fraction's denominator and the denominator to the other fraction's numerator to get the product.

Multiply the numerator and the denominator by the same integer.

If the numerator and the denominator have no common factors other than one, the fraction is already in its simplest form.

The bar or line that separates the numerator from the denominator in fractions is known as the solidus.

Multiply the numerator of one fraction to the other then multiply the denominator of one fraction to the other . Then reduce if possible.

We call that cross multiplying.

Yes. If the numerator and denominator of a fraction are prime, the fraction is in simplest form. The reason is that each number has only two factors, 1 and the number itself. For that reason, it is not possible for the numerator and denominator to have any factors (other than 1) in common.

Exactly the other way around: Divide the numerator by the denominator, and the result will give you the decimal form of the fraction.
