MATHS - Numbers - Cancelling (Simplifying) Fractions

The video 'Equivalent Fractions' teaches how to rewrite fractions by changing the numerator and denominator without altering the fraction's value. This is done by multiplying or dividing both parts by the same number. Simplifying fractions involves a similar process called reduction, where the numerator and denominator are divided by a common factor. The video emphasizes the importance of simplification and provides practice exercises to find the highest common factor and simplify fractions to their simplest form. It concludes with additional practice opportunities.

What is the main method used to create equivalent fractions?

• Multiplying or dividing both the numerator and denominator by the same number

• Subtracting the same number from both the numerator and denominator

• Changing the numerator only

• Adding the same number to both the numerator and denominator

Why is it important to find the highest common factor when simplifying fractions?

• To add fractions together

• To make the fraction larger

• To ensure the fraction is in its simplest form

• To change the fraction to a decimal

What is the first step in simplifying a fraction?

• Subtract the numerator from the denominator

• Add 1 to the denominator

• Find the highest common factor of the numerator and denominator

• Multiply the numerator by 2

What should you do after finding the highest common factor in a fraction?

• Add the HCF to the numerator

• Divide the numerator and denominator by the HCF

• Subtract the HCF from the denominator

• Multiply the numerator and denominator by the HCF

What indicates that a fraction is in its simplest form?

• The numerator is an even number

• The fraction cannot be divided or reduced any further

• The numerator is larger than the denominator

• The denominator is a prime number
