This exercise helps with comparing fractions using mental arithmetic. All of the fractions in it are simple enough that you should be able to work out which is largest in your head.

< is less than.

> is greater than.

To compare fractions the denominator must be the same. Find the lowest common multiple (LCM) of both denominators.

*The LCM is the lowest number that is in both of the times tables of the denominators*.

All of the questions in this exercise only need you to change one fraction.

Muliply the denominator of the fraction with the lowest denominator by the number that will increase it to the LCM. Then multiply the numerator by the same number.

Now that both fractions have the same denominator you can compare them by using the numerators.

**Remember:**

< is less than.

> is greater than.

**Game Over!**

Your 60 seconds is up.
