The divisibility rule is a way to determine whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 85.
The divisibility rule for 85 helps us determine if a number is divisible by 85 without performing division. Check whether 2890 is divisible by 85 with the divisibility rule.
Step 1: Check if the number is divisible by both 5 and 17. For 2890, since the last digit is 0, it is divisible by 5.
Step 2: Add the digits of the number to see if the sum is divisible by 17. 2 + 8 + 9 + 0 = 19, which is not divisible by 17.
Since 2890 is divisible by 5 but not by 17, it is not divisible by 85.
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 85.
The divisibility rule of 85 helps us to quickly check if a given number is divisible by 85, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes that will help you avoid them.
Is 425 divisible by 85?
Yes, 425 is divisible by 85.
To check if 425 is divisible by 85, apply the following steps:
1) Divide the number by 5 to check if it's divisible by 5, 425 ÷ 5 = 85.
2) Now check if 85 is divisible by 17 (since 85 = 5 x 17).
3) 85 ÷ 17 = 5, which is a whole number. Therefore, 425 is divisible by 85.
Check the divisibility rule of 85 for 1700.
Yes, 1700 is divisible by 85.
To check if 1700 is divisible by 85, follow these steps:
1) Divide the number by 5 to check if it's divisible by 5, 1700 ÷ 5 = 340.
2) Now check if 340 is divisible by 17.
3) 340 ÷ 17 = 20, which is a whole number. Therefore, 1700 is divisible by 85.
Is 510 not divisible by 85?
Yes, 510 is not divisible by 85.
To determine divisibility, perform the following steps:
1) Divide the number by 5 to check divisibility, 510 ÷ 5 = 102.
2) Check if 102 is divisible by 17.
3) 102 ÷ 17 = 6 with a remainder, so 510 is not divisible by 85.
Can 850 be divisible by 85 following the divisibility rule?
Yes, 850 is divisible by 85.
To check if 850 is divisible by 85, follow these steps:
1) Divide the number by 5 to check divisibility, 850 ÷ 5 = 170.
2) Now check if 170 is divisible by 17.
3) 170 ÷ 17 = 10, which is a whole number. Therefore, 850 is divisible by 85.
Check the divisibility rule of 85 for 1530.
No, 1530 is not divisible by 85.
To determine divisibility, use the following process:
1) Divide the number by 5 to check divisibility, 1530 ÷ 5 = 306.
2) Check if 306 is divisible by 17.
3) 306 ÷ 17 = 18 with a remainder, so 1530 is not divisible by 85.
