**What are the types of number that can form RATIO?**

Integer and Fraction

Odd Numbers, Even Numbers, Prime Numbers, Perfect Square Numbers and Perfect Cube Numbers.

**NOTE:**

1) '0' is an even number.

**Why?**0 / 2 will give u NO remainder. get it???

'2) 1' is not a Prime Number.

**Why?**since Prime Number means that Number that can be divided exactly by '1' and 'itself' which means that 'itself' must not be equal to '1' .

**Another explaination:**'itself' can be any Postive Integer Number but not '1'
