-9 1/8 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn mixed numbers and decimals. A mixed number combines a whole number and a fraction. In this case, -9 1/8, the whole number is -9, and the fraction 1/8 represents a part of the whole. A decimal is a way to represent numbers that are not whole, 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.

What is -9 1/8 as a decimal?

-9 1/8 as a decimal

 

 

Answer

-9 1/8 in decimals can be written as -9.125. It is a terminating decimal, meaning it ends after a finite number of digits.

 

Explanation

To convert -9 1/8 into a decimal, we need to separate the whole number and the fractional part. The whole number is -9. For the fractional part, 1/8, we'll use division to find its decimal form.

 

Step 1: Identify the numerator and denominator. Here, the numerator is 1, and the denominator is 8.

 

Step 2: Divide 1 by 8. Since 1 is smaller than 8, the result will be a decimal. Add a decimal point and zero to the dividend to make it 10, and place a decimal point in the quotient.

 

Step 3: Divide 10 by 8, which gives 1 as the quotient and a remainder of 2.

 

Step 4: Bring down another 0 to make it 20 and divide by 8, which results in 2 as the quotient with a remainder of 4.

 

Step 5: Bring down another 0 to make it 40 and divide by 8, resulting in 5 as the quotient with no remainder. Thus, 1/8 as a decimal is 0.125. Combining this with the whole number, -9.

 

We get -9.125 as the decimal representation of -9 1/8.
