To find a two-digit number multiplied by a one-digit number that equals 27, we can consider the factors of 27. The two-digit number must be 27 divided by a one-digit factor. The valid combinations are 27 = 9 × 3, where 9 is a one-digit number, and 27 divided by 3 gives us 9, which is also a one-digit number. Therefore, a valid two-digit number multiplied by a one-digit number to get 27 does not exist since 27 itself is a two-digit number.

What is 1 digit number?
A one digit number is a number with only one number. For example: 12 is a two digit number. It has two numbers. 3 is a one digit number because it only has one number.
How many 4 digit combinations can be made from these 3 numbers 2-6-5?
Assuming you're allowed to repeat numbers, the answer is 81. For each digit, you have three choices: 2, 5, and 6. So there are three one-digit numbers you can make, and each one digit number can be combined with any of three other digits to make a two-digit number, giving 9 (3 times 3) possibilities. Now you can take any of the nine two-digit numbers as the tens and ones places in the four-digit number and any other two-digit number as the thousands and hundreds places, which gives 81 (9 times 9) possibilities. If you can't repeat numbers, the answer is zero because you don't have enough numbers to fill all the digits.
How is multiplying by multi-digit numbers similar to multiplying by two-digit numbers?
Multiplying by multi-digit numbers is similar to multiplying by two-digit numbers in that both processes involve breaking down the numbers into place values and multiplying each digit by each digit in the other number. The key similarity lies in the application of the distributive property, where each digit in one number is multiplied by each digit in the other number, and then the products are added together to get the final result. This process is consistent whether you are multiplying by a two-digit number or a multi-digit number.
How do you decide if a 2 digit number is a multiple of a 1 digit number?
To determine if a two-digit number is a multiple of a one-digit number, you can divide the two-digit number by the one-digit number. If the result is an integer (with no remainder), then the two-digit number is a multiple of the one-digit number. Alternatively, you can check if the two-digit number ends in a digit that confirms divisibility by the one-digit number (for example, even numbers for 2, ending in 0 or 5 for 5, etc.).
What is the ratio of the number of one-digit prime numbers and the number of one-digit composite numbers?
The ratio of the number of one-digit prime numbers to the number of one-digit composite numbers is one to one. The one-digit prime numbers are 2, 3, 5, and 7. The one-digit composite numbers are 4, 6, 8, and 9. Therefor, the ratio is 4:4, which simplifies to 1:1.

How many 5 digit combos in 30 numbers?
The answer will depend on how many digits there are in each of the 30 numbers. If the 30 numbers are all 6-digit numbers then the answer is NONE! If the 30 numbers are the first 30 counting numbers then there are 126 combinations of five 1-digit numbers, 1764 combinations of three 1-digit numbers and one 2-digit number, and 1710 combinations of one 1-digit number and two 2-digit numbers. That makes a total of 3600 5-digit combinations.

In a certain two-digit number the tens' digit exceeds the units' by 5 What is the number if it is known that the number is equal to ten times the sum of the digits?
The two digit numbers in which the tens digit is five greater than the units digit are:5061728394The number we are looking for is ten times the sum of its digits, and so must be a multiple of 10. The only one of the above numbers which fits this is 50, as 5 is five greater than 0, and 50 = 10 x (5+0).
