It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of the whole. It has two parts: the 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 8. A decimal is a way to represent a 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 those to the right represent the fractional part.
-3/8 in decimals can be written as -0.375. It is a terminating decimal, meaning it ends after a few digits.
To convert -3/8 into a decimal, we will use the division method. Here, as 3 is smaller than 8, we will take the help of the decimal method, which will give us -0.375. 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 (8) will be taken as the divisor.
Step 2: As 3 is smaller than 8, it can't be divided, so we will take the help of decimals. We will add 0 to the dividend, making 3 as 30 and adding a decimal point in the quotient place.
Step 3: Now that it is 30, we can divide it by 8. Let's see how many times 8 makes 30.
Step 4: 30 is not a multiple of 8, so we will look for the nearest number that is 8 × 3 = 24. We will write 3 in the quotient place and subtract 24 from 30 to get 6.
Step 5: Bring down another 0 in the dividend place, making it 60, and then repeat the division process. 8 goes into 60 seven times (8 × 7 = 56). Subtract 56 from 60 to get 4.
Step 6: Bring down another 0, making it 40, and divide by 8. 8 goes into 40 five times (8 × 5 = 40), leaving no remainder. The process ends here, making it a terminating decimal.
The answer for -3/8 as a decimal is -0.375.
