Exploring Fractions in Lowest Terms

The video tutorial explains how to determine if a fraction is in its lowest terms and how to reduce fractions to their simplest form. It provides examples to illustrate the process of finding the highest common factor (HCF) and using it to simplify fractions. The tutorial also introduces the repeated division method for reducing fractions and concludes with a recap of the key points.

What is a fraction in its lowest terms?

• When the numerator and denominator are equal

• When the numerator and denominator have no common factor other than one

• When the numerator is greater than the denominator

• When the fraction is a whole number

Which of the following fractions is in its lowest terms?

• 8/12

• 4/7

• 10/25

What are the common factors of 8 and 12?

• 1, 2, 3, 4, 6, 12

• 1, 2, 4, 8

• 1, 2, 4

How do you reduce a fraction to its lowest terms?

• Subtract the numerator from the denominator

• Add the numerator and denominator

• Divide the numerator and denominator by their HCF

• Multiply the numerator and denominator by their HCF
