Basics on the topic Fractions on a Number Line — Let's Practise!

Learn with Razzi about how to mark fractions on a number line!

Transcript Fractions on a Number Line — Let's Practise!

Razzi says get these items ready because today we're going to practise fractions on a number line. It's time to begin! Use the number line to plot one half. Pause the video to work on the problem and press play when you are ready to see the solution! Divide the number line into two parts matching the denominator and count forward one part for the numerator. One-half goes here! Did you also label one half here? Let's tackle the next problem! Use the number line to plot three quarters. Pause the video to work on the problem and press play when you are ready to see the solution! Divide the number line into four parts matching the denominator and count forward three parts for the numerator. Three-quarters goes here! Did you also label three-quarters here? Let's tackle the final problem! Use the number line to plot three-thirds. Pause the video to work on the problem and press play when you are ready to see the solution! Divide the number line into three parts matching the denominator and count forward three parts for the numerator. Three-thirds goes here! Three-thirds is the same as one whole! Did you also get label three-thirds here? Razzi had so much fun practising with you today! See you next time!

Would you like to apply the knowledge you’ve learnt? You can review and practice it with the tasks for the video Fractions on a Number Line — Let's Practise!.
  • Where is one half found?

    Hints

    First, partition the number line into the number of parts shown by the denominator.

    In $\frac{1}{2}$, the denominator is 2, so you should make sure that the number line is split into 2 equal parts.

    When the number line is split into 2 equal parts, it looks like this.

    Solution

    $\frac{1}{2}$ would go exactly in the middle from zero to one, half way along.

  • Can you label the number line?

    Hints

    The fraction line has been partitioned into 4 parts, it is in quarters.

    The first blank space is one step on the fraction line. Look for the fraction where there is a 1 in the numerator.

    Remember, the top number in the fraction is the numerator and the bottom number in the fraction is the denominator.

    Solution

    Here you can see $\frac{1}{4}$ and $\frac{3}{4}$ correctly placed on the number line.

  • What fraction is on the number line?

    Hints

    How many parts has the fraction line been separated into? This is the denominator.

    How many steps along the number line have been counted to reach the gap? This is the numerator.

    Solution

    The missing fraction on the line is $\frac{3}{4}$.

  • Identify the missing fraction.

    Hints

    How many parts has the fraction line been separated into? This is the denominator.

    How many steps along the number line have been counted to reach the gap? This is the numerator.

    Here we would mark on $\frac{4}{7}$ because the fraction line has 7 parts and this point is 4 steps along.

    Solution

    The missing fraction on this number line is $\frac{2}{7}$.

    There are 7 parts of the number line so this is the denominator. The fraction is 2 jumps along so this is the numerator.

  • Where would each fraction go?

    Hints

    How many parts has the number line been partitioned into? This is what the denominator is.

    To find where each fraction should go, count forwards along the number line by the numerator.

    Solution

    This is the correct position of the fractions.

  • What are the missing fractions?

    Hints

    The numerator is always the top part of a fraction.

    The denominator is always the bottom part of a fraction.

    When we mark a fraction on a number line, we can find the denominator by seeing how many parts the line is divided into.

    We can find the numerator by counting how many jumps to the fraction.

    Solution

    The fractions can be seen on the image here.
