How do you write 14.23 in two ways?
14.23 = 1423/100 or as 14 and 23/100
Why isn't 3.14 an irrational number?
A rational number is a real number which can be expressed as a division of two integers. A real number which is not rational is called irrational. Since 3.14 = 314/100 and 314 & 100 are integers it is a rational number.
What are the pairs of prime factorization with a difference of 2 in 100?
The prime factorization of 100 is 2x2x5x5. There are no pairs of prime factorization with a difference of two in the number 100.
What is 15000 x 100?
15000 x 100 is equal to 1,500,000. This is because when you multiply a number by 100, you are essentially adding two zeros to the end of the number. In this case, 15,000 with two additional zeros becomes 1,500,000.
How many three digit numbers can be formed such that the sum of the digits is 6?
21 ways assuming no leading zeros, that is the smallest possible number with three digits is 100 Otherwise if leading zeros are allowed, it is 28 ways. For three digit numbers the first digit can be 1-6. Leaving the remaining two digits to be 6-value_of_first_digit. For first digit 6, the remain two digits sum to 0 which means they can only be 00, ie the number 600 - 1 number For first digit 5, the remain two digits sum to 1 which means they can be 01 or 10, ie the numbers 501, 510 - 2 numbers For first digit 4, the remain two digits sum to 2 which means they can be 02. 11, 20, ie the numbers 402, 411, 420 - 3 numbers etc It can be seen that the number of ways of making a two digit number (with leading zeros) sum to a number less than 10 is the required sum plus 1. So for the remaining first digits, the number of ways are: 3 -> 4 ways, 2 -> 5 ways, 1 -> 6 ways. Thus the total number of ways is 1 + 2 + .. + 6 = 21 If leading zeros are permitted, so that, for example, 060 (60) and 006 (6) are considered as three digits numbers, then there are a further 7 ways with a first digit of 0, making a total 28 ways.
