What does digit total less than 10 mean?
According to the numerical puzzler, Digit total means adding up the digits in the number and then seeing if it is less than ten. Eg. 1111 = 1+1+1+1 = 4 and so is less than 10. 76 would be 7+6 = 13 and so would not be less than 10. Hope this helps?
What is a common multiple of 3 and 4 digit total 9 less than 50?
To find a common multiple of 3 and 4 that totals 9 less than 50, we first need to list out the multiples of 3 and 4. Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, and multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. The common multiples are numbers that appear in both lists. The common multiple that totals 9 less than 50 is 36.
How many 8 digit number are there in total?
The first 8 digit number is 10,000,000, the last is 99,999,999 which means there are 90,000,000 8 digit numbers
How many seven digit numbers contain the number seven at least once?
4,748,472 Confirmed using the following C# function string sTemp; int total = 0; for (int i = 1000000; i < 10000000; i++) { sTemp = i.ToString(); if (sTemp.Contains("7")) { total++; } } label1.Text = total.ToString();
How many 5 digit combinations are there from 1-20?
To find the number of 5-digit combinations from 1 to 20, we first calculate the total number of options for each digit position. Since the range is from 1 to 20, there are 20 options for the first digit, 20 options for the second digit, and so on. Therefore, the total number of 5-digit combinations is calculated by multiplying these options together: 20 x 20 x 20 x 20 x 20 = 3,200,000 combinations.
How do you know how many places are in fifty million without writing the number in standard?
To determine how many places are in fifty million without writing it in standard form, you can break it down by understanding the value of each digit. Fifty million can be expressed as "fifty" times "one million." Since one million is represented by the digit "1" followed by six zeros (1,000,000), fifty million has the digit "5" followed by seven places total (5,000,000). Therefore, fifty million has eight digits in total, indicating it has eight places.
Is 261 a multiple of 3?
Yes. Digit total is 9 which is a multiple of 3 so it is too.
What is a common multiple for 2 4 and 7 and is a digit total of 11?
To find a common multiple for 2, 4, and 7 with a digit sum of 11, we first need to find the multiples of each number. The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. The multiples of 7 are 7, 14, 21, 28, 35, and so on. By examining the lists, we find that the number 28 is a common multiple for 2, 4, and 7 with a digit sum of 11.
What is the multiple of three out of these numbers 285770126176410452650?
I'll guess those are three-digit numbers. The way to find if a number is a multiple of 3 is to total its digits. If that total is a multiple of 3, the whole number is a multiple of 3. 285 and 126, yes. 770, 176, 410, 452, 650, no.
The sum of the digits is 11 the tens digit is 3 more than the ones digit what is the total?
There are multiple answers. The only criteria is that the last digit be one third of the second to last ( the tens digit ). So, 731 works as does 362 and 1,631, 2,162 and 11,162. You can also do 111,111,131.
How many three digits counting numbers are multiple of 2?
Three-digit counting numbers range from 100 to 999. To find how many of these are multiples of 2, we note that the smallest three-digit multiple of 2 is 100, and the largest is 998. The sequence of three-digit multiples of 2 can be represented as 100, 102, 104, ..., 998, which forms an arithmetic sequence with a common difference of 2. The total number of terms in this sequence can be calculated as ((998 - 100) / 2 + 1), resulting in 450 three-digit counting numbers that are multiples of 2.
What is an easier way to produce a three-digit number that has 3 as a factor?
Easier than what? The easiest way to produce a three-digit number that is a multiple of 3 (has 3 as a factor) is to make sure the digits total to a multiple of 3. 123, 555, 498 are all multiples of 3.
What is the common multiple of 4 and 6 with two digits total ot 12?
48
What is a 4 digit number that is a multiple of 2 and if you take half you get a multiple of 3?
2010Answer 2If you half it and you get a multiple of 3, then what you are saying is it is a multiple of 6 (2 x 3 = 6).So you want a 4 digit number, a number between 1000 and 9999, which is a multiple of 6.The lowest is 1002 (= 6 x 167), followed by 1008, 1014, 1020 ... etc. up to 9996 (= 6 x 1666).So, there are a total of 1500 such numbers.
How many two-digit counting numbers are less than 30 or a multiple of 20?
To find the two-digit counting numbers less than 30, we consider the numbers from 10 to 29, which gives us 20 two-digit numbers. The multiples of 20 that are two-digit numbers are 20. Since 20 is already included in the count of two-digit numbers less than 30, the total remains 20. Therefore, there are 20 two-digit counting numbers that are either less than 30 or a multiple of 20.
How do you estimate by rounding each number to its leading digit?
To estimate by rounding each number to its leading digit, first identify the most significant digit in each number. Then, round that digit to the nearest multiple of ten based on its place value. For example, if you have the number 473, the leading digit is 4, which rounds to 400. Once all numbers are rounded this way, you can sum them for an estimated total.
How are binary numbers changed to decimal numbers?
Starting with the number just before the "decimal/binary" point and going left: you leave the first digit as it is, add 2 times the digit to its left, add 4 times the digit to its left, add 8 times the digit to its left, and so on to the end. The multiple is doubled each time. If you have digits to the right of the point, you add 1/2 times the first digit add 1/4 times the digit to its right, add 1/4 times the digit to its right, and so on to the end. The multiple is halved each time. The grand total is the equivalent decimal number.
