Question

1. Write the divisibility test of 4 with examples.

2. Write the divisibility test of 9 with examples.​

Answer 1

Step-by-step explanation:

in the last two digits of a number is divisible by 4 ,then that number will multiple with 4 ,divisible of 4 is complete. now,example - take a number like 2308 ,consider the last two digits i.e .08 as 08 is divisible by 4

sums of a digit of of a number is divisible by 9 , example which are divisible by 9 are as follows. the number 51984 is divisible by 9 because the sum of this digits 5+1+9+8+4 = 27 is divisible by 9

hope it helps you

Answer 2

Answer:

1) A number is divisible by 4 if the last two digits of the number are divisible by 4.

2) A number is divisible by 9 if the sum of the digits is divisible by 9.

Step-by-step explanation:

1) Example of Divisibility test of 4:-

Let's take a number 5,554.

The last two digits of the number are 54 and they are not divisible by 4.That means the number 5,554 is not divisible by 4.

2) Example of divisibility test of 9:-

Taking the number 1,764 we will check it's sum.

We get 1 + 7 + 6 + 4 = 18. Since the sum of digits is 18 and is divisible by 9 therefore the number 1,764 is divisible by 9.
