Answer 2

The numbers which are divisible by 4 in between 1 to 20 include the following:

 4, 8, 12, 16, 20

A total of five numbers are divisible by 4 in between 1 to 20.

To find the percentage of numbers : 5 ÷ 20 × 100 = 25% 

A helpful rule for 4: if the last two digits of a whole number are divisible by 4 then the entire number is divisible by 4

For example we take the number 9,316, since the last two digits make up 16 and 16 come in the table of 4 so it is said to be divisible by 4 which means 9,316 as a whole number is divisible by 4.
