Are the last three digits divisible by 8
To check whether the last two digits of a number are divisible by 4, we need to check if the remainder when dividing the number by 4 is 0. Here's how to do it:
1. Take the number and find the remainder when dividing it by 4.
2. If the remainder is 0, then the last two digits are divisible by 4. Otherwise, they are not.
In the case of number 120:
1. Divide 120 by 4: 120 ÷ 4 = 30.
2. The remainder is 0, so the last two digits (20) are divisible by 4.
To check whether the last three digits of a number are divisible by 8, we need to check if the remainder when dividing the number by 8 is 0. Here's how to do it:
1. Take the number and find the remainder when dividing it by 8.
2. If the remainder is 0, then the last three digits are divisible by 8. Otherwise, they are not.
In the case of number 120:
1. Divide 120 by 8: 120 ÷ 8 = 15 with a remainder of 0.
2. The remainder is 0, so the last three digits (120) are divisible by 8.
To check whether the sum of the digits of a number is divisible by 9, we need to find the sum of the individual digits and check if the sum is divisible by 9. Here's how to do it:
1. Take the number and add up all of its individual digits.
2. If the sum is divisible by 9, then the sum of the digits is divisible by 9. Otherwise, it is not.
In the case of number 120:
1. The sum of the digits is 1 + 2 + 0 = 3.
2. The sum is not divisible by 9, so the sum of the digits (3) is not divisible by 9.
Therefore:
- The last two digits of 120 are divisible by 4.
- The last three digits of 120 are divisible by 8.
- The sum of the digits of 120 is not divisible by 9.
