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) and denominator (number below). A mixed fraction contains a whole number and a fractional part. A decimal is a way to represent the number that is not whole by using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole part, and those to the right represent the fractional part.
-7 3/8 in decimal form can be written as -7.375.
To convert -7 3/8 into a decimal, we first deal with the fractional part 3/8. We will use the division method to convert 3/8 into a decimal. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator. Here, the numerator (3) will be taken as the dividend, and the denominator (8) will be taken as the divisor.
Step 2: Perform the division 3 ÷ 8. Since 3 is smaller than 8, we add a decimal point and a zero to the dividend, making it 30.
Step 3: Divide 30 by 8. 8 goes into 30 three times (3 × 8 = 24). Write 3 in the quotient place.
Step 4: Subtract 24 from 30, which gives 6. Bring down another 0, making it 60.
Step 5: Divide 60 by 8. 8 goes into 60 seven times (7 × 8 = 56). Write 7 in the quotient, and subtract 56 from 60, leaving 4.
Step 6: Bring down another 0, making it 40. Divide 40 by 8, which goes 5 times (5 × 8 = 40), leaving no remainder.
Thus, 3/8 as a decimal is 0.375. Combining this with the whole number part, -7, gives us -7.375.
