Question

Quadra gets £120 for her birthday.She spends 3/4 and saves the rest.How much does she save?

Answer 1

To find out how much Quadra spent, we can use this equation:

• Total amount of money × fraction spent = amount left

Fitting the numbers into the equation would look like this:

• £120 × 0.75 = £90

Why do we multiply by 0.75?

We multiply by 0.75 because it is equivalent to 3/4.

If we now know that Quadra spent £90, we can subtract that from her total amount of money to get the amount of money she saved.

• £120 - £90 = £30

Therefore, Quadra saved £30.
