Let's find all the prime numbers.
1,3,5,7,9,11,13,15,17,19
They are not divisible by 2.
Put that into a fraction, where the amount of numbers is the numerator and the total amount of numbers is the denominator.
10/20
That is half of 20.
So, 50% of the 20 first natural numbers are prime.
I hope this helps!

x
–
5
=
±
√
3
Add 5 to both sides:
x
=
5
±
√

This breaks into two equations:
x
=
5
+
√
3
and
x
=
5
−

Use the square root on both sides:
x
–
5
=
±
√
3
Add 5 to both sides:
x
=
5
±
