Explain how you know if a number can be divided evenly.
If its even.
(ಠ_ಠ)
Numbers "dividing evenly" has nothing to do with the numbers being even.
A number is said to divide into another evenly, if there is a zero remainder after the division.
e.g. 15 ÷ 3 = 5 , (note none of the numbers are even)
15 is evenly divisible by 3
but 18 ÷ 4 = 4 with a remainder of 2
(note both numbers are even, but 18 does not divide evenly by 4)
To determine if a number can be divided evenly, you need to check if the remainder of the division operation is zero. Here's how you can do it:
1. Select the number that you want to divide, which is called the dividend.
2. Choose the number you want to divide by, which is the divisor.
3. Perform the division operation by dividing the dividend by the divisor.
4. If the remainder of the division is zero, then the number can be divided evenly. This means that the number is divisible by the divisor.
5. If the remainder is not zero, then the number cannot be divided evenly. It is not divisible by the divisor.
For example, let's see if 12 can be divided evenly by 3:
1. Dividend = 12, Divisor = 3
2. Perform the division: 12 ÷ 3 = 4
3. The remainder of the division is 0.
4. Since the remainder is zero, 12 can be divided evenly by 3.
On the other hand, let's see if 15 can be divided evenly by 4:
1. Dividend = 15, Divisor = 4
2. Perform the division: 15 ÷ 4 = 3.75 (rounded to two decimal places)
3. The remainder of the division is not zero.
4. Since the remainder is not zero, 15 cannot be divided evenly by 4.
