13/40 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part from the whole. It has two parts: numerator (number on the top) here, 13 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 40. A decimal is a way to represent the number that is not whole, using a (.) or a decimal to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and that to the right represents the fractional part.

What is 13/40 as a decimal?

13/40 as a decimalAnswer

 

13/40 in decimals can be written as 0.325. It is a terminating decimal, meaning it does not repeat the same digit infinitely.

 

Explanation

 

To get 13/40 in decimal, we will use the division method. Let's see the step-by-step breakdown of the process:

 

Step 1: Identify the numerator and denominator because the numerator (13) will be taken as the dividend and the denominator (40) will be taken as the divisor.

 

Step 2: Since 13 is smaller than 40, it can't be divided directly. We will add a decimal point and a 0 to the dividend, making it 130.

 

Step 3: Now that it is 130, we can divide it by 40. Let's see how many times 40 fits into 130.

 

Step 4: 40 goes into 130 three times, since 3 × 40 = 120. Write 3 in the quotient place and subtract 120 from 130 to get 10.

 

Step 5: Bring down another 0 in the dividend place to make it 100, and then divide again. 40 goes into 100 two times, as 2 × 40 = 80. Subtract 80 from 100 to get 20.

 

Step 6: Bring down another 0 to make it 200. 40 goes into 200 five times, as 5 × 40 = 200. Now, subtract 200 from 200 to get 0.

 

Since the remainder is 0, the division ends, and the answer for 13/40 as a decimal is 0.325.
