There are nine ones in the answer.
12345679 × 9 = 111111111
That means multiply it by 2. If your tens digit is 3, your ones digit is 6.
The number is 44; 4 + 4 = 8.

ones
2,4,6,8,and 0 are divisible by 2 in the ones digit. Zero is only divisible in a number with 2 digits or more. 0 itself is not divisible by 2.
That means multiply it by 2. If your tens digit is 3, your ones digit is 6.

Multiplying a 2-digit number by a 1-digit number involves multiplying the digits in the ones and tens place and then adding the products. Similarly, multiplying a 3-digit number by a 1-digit number follows the same principle, where you multiply the digits in the ones, tens, and hundreds place and then add the products. The main difference is that in the latter case, you are dealing with three sets of digits to multiply and add, whereas in the former, you only have two sets of digits.
The number is 44; 4 + 4 = 8.

The ones digits of the 2s facts follow a pattern in which every second multiple of 2 ends in either 0, 2, 4, 6, or 8. This is because when you multiply any number by 2, the ones digit will always be even. Therefore, the ones digits of the 2s facts are 0, 2, 4, 6, and 8.
If the original number was even, the ones place will be zero; otherwise it will be 5.
ten ones with an infinite number of zeroes.
Any even number.
Ignore the decimal points and multiply the numbers to give the product: 308*29 = 8932Count the number of digits AFTER the decimal points in the two numbers. Two in the first and one in the second, making three in all.That is the number of digits after the decimal point that you want in the answer. So insert the decimal point that many digits from the end of the product.Thus 8932 becomes 8.932Done!
