Connecting fractions, decimals and percentages
There is a relationship between decimals, fractions and percentages. Whilst each of these areas is often taught separately, there is value in demonstrating how fractions, decimals and percentages are related.
Decimals are a convenient and useful way of writing fractions with denominators 10, 100, 1000 and so on.
So \(\dfrac{3}{10}\) is written as 0.3, \(\dfrac{2}{100}\) is written as 0.02, \(\dfrac{11}{100}\) is written as 0.11 and we write \(\dfrac{434}{1000}\) as 0.434 in decimal form.
This is best done with simple, familiar fractions, decimals and percentages to start with.
Even though there are different ways of writing a number, the value remains the same.
