How many even 3-digit numbers can be formed from digits 0 1 2 4 5 7 9 if each digit can be used only once?
To solve this question, two cases must be considered:Case 1: The three-digit even number ends with 0.If the three-digit number ends with 0, then the number must be even. After the digit 0 is used, six digits remain. After any one of these six digits is chosen to be the first digit, five digits remain. To complete the number, any of the five remaining digits could be chosen to be the second digit of the number.___6___ * ___5___ * ___1___ = 30 three-digit even numbers ending in 0.1st digit-------2nd digit----3rddigit (0)Case 2: The three-digit even number does not end with 0.If the three-digit number does not end with 0, it can end with 2 or 4. Therefore, there are two possibilities for the third digit. The first digit could be any of the remaining digits, EXCEPT 0: if 0 were the first digit, it would not be a three-digit number. Therefore, there would be five possible digits for the first digit. 0 could be used as the second digit, along with the four remaining digits that were not previously used.___5___ * ___5___ * ___2___ = 50 three-digit even numbers not ending in 0.1st digit-------2nd digit-----3rddigit (0)The total number of three-digit even numbers is 80, since 30 three-digit even numbers ending in 0 plus 50 three-digit even numbers not ending in 0 equals 80.
Is 140 a even number?
Yes. If the last digit is divisible by 2 (that is if it is 0, 2, 4, 6 or 8) then the whole number is divisible by 2 and even. The last digit of 140 is 0 which is an even digit, so 140 is even.
What is the smallest 1 digit even number?
zero is the smallest even number (0)
When is a number a multiple of 4?
When the tens digit is even and the units digit is 0, 4 or 8 or the tens digit is odd and the units digit is 2 or 6.
What is the sum of the smallest 6-digit even number and the largest 6-digit odd number?

Is 140 a even number?
Yes. If the last digit is divisible by 2 (that is if it is 0, 2, 4, 6 or 8) then the whole number is divisible by 2 and even. The last digit of 140 is 0 which is an even digit, so 140 is even.
If the ones digit is 0 or even number?
0 is to be neither odd or even. But numbers like 10,20 are even. So, 0 is considered even.
What is the ones digit in even numbers can be?
The ones digit in even numbers can be any of the following: 0, 2, 4, 6, or 8. This is because even numbers are divisible by 2, meaning they can be expressed as 2 multiplied by another integer. The ones digit is the digit in the ones place of a number, which can range from 0 to 9.
What is the largest two digit even numbers?
The largest two-digit even number is 98. In the decimal system, each digit can range from 0 to 9, but for a two-digit number, the first digit cannot be zero. Since we are looking for an even number, the last digit must be an even number, which leaves us with 0, 2, 4, 6, or 8. Among these options, 8 is the largest even digit, resulting in 98 as the largest two-digit even number.
What is the smallest 1 digit even number?
zero is the smallest even number (0)
When is a number a multiple of 4?
When the tens digit is even and the units digit is 0, 4 or 8 or the tens digit is odd and the units digit is 2 or 6.
Is 75432 an even number?
Yes A whole number is even if its least significant digit is even. The least significant digit of a whole number is the digit in the "ones place". In other words, if the digit at the far right is 0, 2, 4, 6 or 8, the number is even.
Is 3500 an even number?
yes because the last digit is a 0
What is the sum of the smallest 6-digit even number and the largest 6-digit odd number?
0
What are the Divisibility rules of 20?
20 = 2 × 10 → The last digit MUST be a 0 → The preceding digit must be even, ie one of {0, 2, 4, 6, 8}.
Is 300 even?
Yes, any number ending with and even digit (0, 2, 4, 6, 8) is even. For example, 9,999,999,999,999,354 is an even number, because the last digit is an even number.Yes, it is.
