Thanks reinout-g
This is exactly the same but it might be easier to follow.

50% of 90
now the % means over 100 and of means x

so just do exactly what the question says

50/100 x 90 =

In computer speak we often use a * instead of a x sign.
That way it is not confusing if there are x es in the questions
