Question Erik thinks of a prime number between 20 and 30. His number is x% of 125. Work out one possible value of x
There are two prime numbers between 20 and 30: 23 and 29.
To find the percentage each number is of 125, you’d divide the number by 125 and move the decimal in the answer 2 places to the right to turn it to percentage notation (from decimal notation), so you’d solve 23/125 and 29/125.
Moving the decimal two places to the right makes this 18.4%
Moving the decimal two places to the right makes this 23.2%
X has two possible values of which you are to pick/use only one: 18.4 and 23.2
