Divisibility Rule of 5
How many three-digit numbers are divisible by 5?
To find out how many three-digit numbers are divisible by 5, we need to count the multiples of 5 within the range of three-digit numbers.
- The first three-digit multiple of 5 is 100, and the last three-digit multiple of 5 is 995.
- To find multiples of 5 between 100 and 995 we divide the difference (995 – 100 = 895) by 5 and add 1. So, 895/5 + 1 = 179 + 1 = 180.
- Therefore, there are 180 three-digit numbers divisible by 5.
How many two digits numbers are divisible by 5?
To find out how many two-digit numbers are divisible by 5, we need to count the multiples of 5 within the range of two-digit numbers, which is from 10 to 99.
- The first two-digit multiple of 5 is 10, and the last two-digit multiple of 5 is 95.
- To find multiples of 5 between 10 and 95 we divide the difference (95 – 10 = 85) by 5 and add 1. So, 85/5 + 1 = 17 + 1 = 18.
- Therefore, there are 18 two-digit numbers divisible by 5.
What is the divisibility test of 5?
The divisibility test of 5 states that a number is divisible by 5 if its last digit is either 0 or 5.
Is there a similar rule for divisibility by 10?
Yes, there is a similar rule for divisibility by 10. A number is divisible by 10 if its last digit is 0.
How to quickly check if a large number is divisible by 5?
To quickly check if a large number is divisible by 5, you only need to look at its last digit. If the last digit is 0 or 5, then the number is divisible by 5.
