MATHS - Numbers - Ordering Fractions & Decimals

The video tutorial explains how to order fractions and decimals by finding a common denominator. It begins by discussing the challenge of comparing fractions with different denominators and suggests converting them to decimals or finding a common denominator. The tutorial then demonstrates finding the lowest common multiple and converting fractions to equivalent forms with a common denominator. Finally, it explains how to order the fractions by comparing numerators and converting them back to their original forms. This method is useful for handling large denominators and is applicable to adding and subtracting fractions.

What is the first step in ordering fractions with different denominators?

• Find a common denominator

• Subtract them from each other

• Convert them to decimals

• Add them together

If you have a fraction 7/10, how do you convert it to have a denominator of 30?

• Multiply both numerator and denominator by 6

• Multiply both numerator and denominator by 5

• Multiply both numerator and denominator by 3

• Multiply both numerator and denominator by 2

How many 5's are there in 30, and what is the equivalent fraction of 3/5 with a denominator of 30?

• 5, 15/30

• 6, 18/30

• 3, 9/30

• 4, 12/30

What is the equivalent fraction of 4/6 with a denominator of 30?

• 24/30

• 20/30

• 18/30

• 15/30

Why is finding equivalent fractions useful beyond ordering?

• It helps in multiplying fractions

• It helps in converting fractions to percentages

• It simplifies fractions

• It is useful for adding and subtracting fractions
