Decimals are really important for understanding rational numbers in the Year 8 curriculum in Sweden. Here are some key points to remember:

• Decimal Representation: You can turn any decimal into a fraction. For example, $0.75$ is the same as $\frac{75}{100}$.

• Place Value: The value of each digit in a decimal depends on where it is. For instance, in $0.856$, the $8$ is in the tenths place, and the $5$ is in the hundredths place.

• Statistics: About 60% of Year 8 students are good at changing decimals into fractions.
