What two digit number are interchanged to form a new two-digit number?
Any two digit number in which: (a) the units digit is not 0, and (b) the two digits are different will form a new 2-digit number when the digits are interchanged.
How is multiplying a 2-digit number by a 1-digit number the same as multiplying a 3-digit number by a 1-digit number and how is it different?
They are the same because they are both multiplication. They also can be the same if the two digit number times by the one digit number equals a three digit number. They are different because the 3 digits number will obviously produce a higher product.
What can you say about the dividend and divisor A three digit number is divided by a one digit number the quotient is a two digit number?
A dividend is is a number to be divided and a divisor is a number to be divided into a dividend. Here the dividend is a three digit number and is divided by a one digit divisor. The quotient or result is a two digit number as stated. So in math terms, we can state that the dividend is a three digit number and that the divisor is a one digit number.
Is a 3-digit number all the digits are different the first and second digits are multiples of 3 the first digit is greater than the second digit?
Not necessarily. Consider 444. The digits are not different. The first and second digits are not multiples of 3 The first digit is not greater than the second digit. In spite of all that, 444 is a 3-digit number

What 3 digit number divided by a 1 digit number gives you a number of 8?
Its Impossible. I say this because anything that is three digits divided by a one digit number that equals 8 is not possible. For example the higher 1 digit number that you can multiply by eight is nine so I did 8x9 and got 72 which is not a three digit number. The lowest three digit number that 8 goes into is 104 which is 13x8 and 13 is not a one digit number. Therefore the problem is impossible. :)
