Understand Denominators of 10 and 100 | Year 4 Maths Resources

What you need to know

Things to remember:

• A fraction is a division, with the top number divided by the bottom number.
• A 10 on the bottom means we divide by 10.
• A 100 on the bottom means we divide by 100.

Remember, we have fancy names for the numbers in a fraction:

$$\frac{5}{100} = \frac{\leftarrow Numerator}{\leftarrow Denominator}$$

A fraction is a way of writing a division, with the top being divided by the bottom.

$$\frac{5}{10}= 5\div10=0.5$$

$$\frac{70}{10}= 70\div10=7$$

$$\frac{80}{10}= 80\div10=8$$

$$\frac{120}{10}= 120\div10=12$$

$$\frac{500}{100}= 500\div100=5$$

$$\frac{700}{100}= 700\div100=7$$

$$\frac{1000}{100}= 1000\div100=10$$

$$\frac{200}{100}= 200\div100=2$$
