KS2 Primary Maths Age 13-17 - Fractions, Decimals and Percentages: Equivalent Fractions and Decimals - Explained

The video tutorial explains how to compare a decimal (0.25) with a fraction (2/5) by converting both to decimals. It demonstrates that 0.25 is smaller than 0.4, which is the decimal equivalent of 2/5. Additionally, it presents an alternative method using visual aids, such as drawing circles divided into fractions, to show that 2/5 is larger than 1/4. The tutorial emphasizes that there are multiple ways to solve such problems, and both methods are valid.

Why is it challenging to compare decimals with fractions directly?

• Decimals and fractions cannot be converted into each other.

• Fractions are always larger than decimals.

• Decimals are always larger than fractions.

• Decimals and fractions are different types of numbers.

What is the decimal equivalent of the fraction 2/5?

• 0.45

• 0.5

• 0.4

• 0.25

How do you convert the fraction 2/5 into a decimal?

• Multiply the numerator and denominator by 5.

• Multiply the numerator by 2 and the denominator by 10.

• Divide the numerator by the denominator.

• Add 0.5 to the fraction.

What visual method did some students use to compare 1/4 and 2/5?

• Drawing squares and dividing them into parts.

• Using a number line to compare the values.

• Drawing circles and shading the respective fractions.

• Using a calculator to find the decimal values.

What conclusion did the students reach using the visual method?

• 1/4 is larger than 2/5.

• 2/5 is smaller than 0.25.

• 2/5 is larger than 1/4.

• 1/4 and 2/5 are equal.
