The smallest two digit prime number is 11 .
11%5E2=121
11%5E2-1=121-1=120 is 1 fewer than the square of the smallest two digit prime number.
The first prime number is 2 .
After that the next primes are 3, 5 , 7 ,etc.
so the fourth prime number is 7 .
The difference between the squares of the fourth and first prime numbers is
7%5E2-2%5E2=49-4=45
120 divided by 45 is 120%2F45=40%2F15=highlight%288%2F3%29 .

Let's list the primes up to the first two-digit one.

A prime is a positive integer other than 1 that has as its only factors
itself and 1.

The first 5 primes are

2,3,5,7,11, and as we see, 11 is the smallest 2-digit prime.

To find my number take 1 fewer than the square of the smallest two digit prime number
The smallest two-digit prime is 11
It's square is 121
1 fewer that 121 is 120

and divide this result 

That is we are to divide 120 ...

by the difference between the squares of the fourth and first prime numbers.
The 4th and 1st prime numbers are 7 and 2.
Their squares are 49 and 4.
The difference between them is 49-4= 45

So we are to divide 120 by 45:

120%2F45=8%2F3

What is my number?
8%2F3
