It is a simple question on decimal conversion. Firstly, we have to learn fractions, mixed numbers, and decimals. A fraction represents a part of the whole. It has two parts: numerator (number on the top) and denominator (number below). A mixed number consists of a whole number and a fraction. A decimal is a way to represent a number that is not whole, using a (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

What is -2 1/2 as a decimal?

Answer

-2 1/2 in decimals can be written as -2.5.

Explanation

To convert -2 1/2 into a decimal, we first understand that it is a mixed number. The whole number here is -2, and the fractional part is 1/2. Let's convert the fractional part into a decimal and then combine it with the whole number.

Step 1: Identify the fractional part, which is 1/2. To convert 1/2 into a decimal, we divide the numerator by the denominator.

Step 2: Divide 1 by 2. Since 1 is smaller than 2, we use decimals to help us.

Step 3: Add a decimal point and a zero to make it 10. Now divide 10 by 2.

Step 4: 2 goes into 10 five times (2 × 5 = 10), so we write 5 in the decimal place.

Step 5: The division gives us 0.5 for the fractional part.

Step 6: Combine the whole number -2 with the fractional decimal 0.5 to get -2.5.

Therefore, the answer for -2 1/2 as a decimal is -2.5.
