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, 7 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.
7/40 in decimals can be written as 0.175. It is a terminating decimal, showing it ends after a few digits.
To get 7/40 in decimal, we will use the division method. Here, as 7 is smaller than 40, we will take the help of the decimal method which will give us 0.175. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (7) will be taken as the dividend and the denominator (40) will be taken as the divisor.
Step 2: As 7 is smaller than 40, it can't be divided directly. Here, we will take the help of decimals. We will add 0 to the dividend, which will make 7 as 70 and add a decimal point in the quotient place.
Step 3: Divide 70 by 40. 40 goes into 70 once, so we write 1 in the quotient place. Subtract 40 from 70 gives 30.
Step 4: Bring down another 0 in the dividend place making it 300. Divide 300 by 40. 40 goes into 300 seven times, so we write 7 in the quotient place. Subtract 280 from 300 gives 20.
Step 5: Bring down another 0 making it 200. Divide 200 by 40. 40 goes into 200 five times, so we write 5 in the quotient place. Subtract 200 from 200 gives 0, completing the division. The division process ends with a remainder of 0. This decimal is called a terminating decimal.
The answer for 7/40 as a decimal will be 0.175.
