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, 17 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.
17/40 in decimals can be written as 0.425. It is a terminating decimal, meaning it does not repeat infinitely.
To get 17/40 in decimal, we will use the division method. Here as 17 is smaller than 40, we will take help of decimal method which will give us 0.425. Let's see the step-by-step breakdown of the process.
Step 1: Identify the numerator and denominator because the numerator (17) will be taken as the dividend and the denominator (40) will be taken as the divisor.
Step 2: As 17 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 17 as 170 and add a decimal point in the quotient place.
Step 3: Now that it is 170, we can divide it by 40. Let's see how many times 40 fits into 170.
Step 4: 40 goes into 170 four times, since 40 × 4 = 160. We write 4 in the quotient place and subtract 160 from 170 to get 10.
Step 5: Bring down another 0 in the dividend place, making it 100, and then divide again by 40.
Step 6: 40 goes into 100 twice, since 40 × 2 = 80. We write 2 in the quotient place and subtract 80 from 100 to get 20.
Step 7: Bring down another 0 in the dividend place, making it 200, and then divide again by 40.
Step 8: 40 goes into 200 five times, since 40 × 5 = 200. We write 5 in the quotient place. The remainder is 0, so the division process stops.
The answer for 17/40 as a decimal will be 0.425.
