From the information given, 60% is equivalent to 18.
We need to find out what 1% is equivalent to, so:
60 = 18
1 = x (where x is the value of 1%)
We now simplify the above equation, so:
60 × x = 18 × 1 → 60x = 18 → x = 18 / 60 → x = 0.3
So 1% is equivalent to 0.3
Therefore 90% will be → 0.3 × 90 = 27
90% of the number is 27
