0 and 5. Every multiple of 5 ends in one of those 2 digits. 5 times any even number ends in 0; 5 times an odd number ends in 5.
0 or 5
You can reduce the number by known factors to make it more manageable. Plus there are tricks for different numbers: If the number is even, then 2 is a factor. If the digits add up to a multiple of 3 then 3 is a factor. If the ones digit is a 5 or 0 (with a tens digit greater than or equal to 1), then 5 is a factor. If the ones digit is a 0 then 10 is a factor. If the digits have the property that the first minus the second, plus the third, minus the fourth, (alternating signs) equals 0, then 11 is a factor. There are other tricks but these factors would be the most common.
2.5 billion in numbers is written as 2,500,000,000. This is because each comma represents a grouping of three digits in the numerical system. The first comma separates the millions place from the thousands place, and the second comma separates the thousands place from the ones place. Therefore, 2.5 billion is equivalent to 2,500,000,000 in numerical form.
32 is an even number (look at the ones place). The only even prime is 2. 95 has 5 as a factor (again look at the ones place). Multiples of 5 have a 0 or 5 in the ones place.That is how you figer out if 32 and 95 in not a prime number.
Tiesonthewall:Not only a lot of numbers, but basically any number that is even will conclude to have 2 as a factor.The even ones.

Answer: 2058 Explanation: Consider the thousandths place. You can place digits 1,2,3,4,5,6 (not 0 as the number would then become a 3-digit). Now consider hundredths place. You can place all the allowed digits ( ie, 0,1,2,3,4,5,6). In the same way you can place all allowed digits in tens and ones place. No. of digits which can be placed in thousandths place: 6 No. of digits which can be placed in hundredths place: 7 No. of digits which can be placed in tens place: 7 No. of digits which can be placed in ones place: 7 Total possible numbers which can be formed: 6 X 7 X 7 X 7 = 2058
2984, 2980
the 3 digits is the ones place the 5 digits is the tenths place the 9 digits is the hundredths place
The "ones" place is always the last digit in any number so multiples of 5 always have either 5 or 0 (zero) in the "ones" digit position.
technically you don't line up the ones. you line up the decimals. you do this because it is necessary to compare place value to place value in order to order.
They are written as numbers usually are. The place value of the digit immediately to the left of the decimal point is ones and the place value of all other digits is ten times the value of the digit to their right.
