Question

divisibility rule of all number 2 to 20 ​

Answer 1

Answer:

The number formed by the last two digits is divisible by 20. 480: 80 is divisible by 20. Subtracting twice the last digit from the rest gives a multiple of 21. 168: 16 − 8 × 2 = 0.

The divisibility rule for two states that any number with the last digit of 0, 2, 4, 6, or 8 will be divisible by 2. Simply put, any even number is divisible by 2. If the number is not an even number, it is not divisible by two
