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, 3 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 80. 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.
3/80 in decimal form can be written as 0.0375. It is a terminating decimal, indicating it has an end.
To convert 3/80 into a decimal, we will use the division method. Here, since 3 is smaller than 80, we will use the decimal method, which will give us 0.0375. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (3) will be taken as the dividend and the denominator (80) will be taken as the divisor.
Step 2: As 3 is smaller than 80, it can't be divided directly. We will add 0 to the dividend, making it 30, and add a decimal point in the quotient place.
Step 3: Now that it is 30, we will see how many times 80 fits into 30. It does not, so we add another 0, making it 300.
Step 4: 80 goes into 300 three times, as 80 × 3 = 240. We write 3 in the quotient and subtract 240 from 300, which gives 60.
Step 5: Bring down another 0 to make it 600. 80 goes into 600 seven times, as 80 × 7 = 560. Write 7 in the quotient and subtract 560 from 600, leaving 40.
Step 6: Bring down another 0 to make it 400. 80 goes into 400 five times, as 80 × 5 = 400, leaving no remainder. The division process stops here, as we have a remainder of 0.
The answer for 3/80 as a decimal is 0.0375.
