Write each fraction in lowest terms. 90/150

Verified step by step guidance
1
Identify the numerator and denominator of the fraction: numerator = 90, denominator = 150.
Find the greatest common divisor (GCD) of 90 and 150. The GCD is the largest number that divides both 90 and 150 without leaving a remainder.
Divide both the numerator and the denominator by the GCD to simplify the fraction.
Write the simplified fraction as \(\frac{\text{numerator} \div \text{GCD}}{\text{denominator} \div \text{GCD}}\).
Verify that the resulting fraction is in lowest terms by checking that the numerator and denominator have no common divisors other than 1.
