Simplifying Fractions with Natural Numerators and Denominators

To simplify the given fractions, let's start by factoring the numerators and denominators to identify common factors that can be canceled out.

a) 8xyz / 24yz

First, let's factor the numerator and denominator: - Numerator: 8xyz = 2 * 2 * 2 * x * y * z - Denominator: 24yz = 2 * 2 * 2 * 3 * y * z

Now, we can cancel out the common factors: - 8xyz / 24yz = (2 * 2 * 2 * x * y * z) / (2 * 2 * 2 * 3 * y * z) = 1/3

b) 30a^2 / 12ab

Let's factor the numerator and denominator: - Numerator: 30a^2 = 2 * 3 * 5 * a * a - Denominator: 12ab = 2 * 2 * 3 * a * b

Cancel out the common factors: - 30a^2 / 12ab = (2 * 3 * 5 * a * a) / (2 * 2 * 3 * a * b) = 5a / 2b

c) 6a - 6b / 12

This expression involves subtraction, so let's simplify it: - 6a - 6b = 6(a - b)

Now, we can simplify the fraction: - 6(a - b) / 12 = 6(a - b) / 12 = (a - b) / 2

Final Results:

a) 8xyz / 24yz = 1/3 b) 30a^2 / 12ab = 5a / 2b c) 6a - 6b / 12 = (a - b) / 2
