Reduce 27/54 to lowest terms.

Both the numerator and denominator are divisible by 9.

27/54 = 3/6 = 1/2

I see now that 54 is divisible by 27.

To reduce a fraction to its lowest terms, you need to simplify the numerator and denominator by finding their greatest common divisor (GCD) and dividing both by it.

So, to reduce 27/54 to lowest terms, first find the GCD of 27 and 54.

To do this, you can find the prime factors of both numbers and determine the common factors. Let's break down 27 and 54:

27 = 3 × 3 × 3
54 = 2 × 3 × 3 × 3

Looking at the prime factorization of both numbers, the common factor is 3 raised to the power of 3, which means the GCD of 27 and 54 is 3 × 3 × 3 = 27.

Now, divide both the numerator and denominator by the GCD:

27 ÷ 27 = 1
54 ÷ 27 = 2

Therefore, 27/54 reduced to lowest terms is 1/2.
