Before we can divide 144 by 9, it’s important to understand what the number 144 represents. 144 is a composite number that is the square of 12. It has several factors, including 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, and 72. These factors can be used to find the prime factorization of 144, which is 2^4 x 3^2.

Division is the process of finding out how many times one number is contained within another number. For example, if we have 12 apples and we want to divide them equally among 3 people, we would divide 12 by 3 to get 4 apples per person. In mathematical terms, we would write this as 12 ÷ 3 = 4.

Now that we have a basic understanding of what division is, we can move on to dividing 144 by 9. To do this, we need to find out how many times 9 is contained within 144. We can do this by using long division.

First, we write 144 as the dividend and 9 as the divisor:

16

9   |   144

24

18

6

Starting from the left, we divide 9 into the first digit of 144, which is 1. Since 9 is less than 10, we can’t divide it into 1, so we move to the next digit, which is 14. We can divide 9 into 14 once, which gives us 9. We write this above the 4.

Next, we multiply 9 by 9, which gives us 81. We write this below 14 and subtract to get 5. We bring down the next digit, which is 4, and we get 54.

We repeat the process by dividing 9 into 54, which gives us 6. We write this above the 4, and we multiply 9 by 6 to get 54. We write this below 54 and subtract to get 0. Since there are no more digits to bring down, we have the final result:

16

Therefore, 144 divided by 9 equals 16.
