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 1 1/2 represents how many parts out of the whole, and the denominator (number below) shows how many parts make the whole, here it is 2 for the fractional part. 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 those to the right represent the fractional part.

What is 1 1/2 as a decimal?

Answer

1 1/2 in decimals can be written as 1.5. It is a terminating decimal, meaning it does not repeat infinitely.

Explanation

To get 1 1/2 in decimal, we will convert the fraction part 1/2 to decimal and add it to the whole number 1. Let's see the step-by-step breakdown of the process:

Step 1: The whole number part is 1.

Step 2: For the fractional part 1/2, identify the numerator and denominator. The numerator (1) is the dividend, and the denominator (2) is the divisor.

Step 3: Perform the division 1 ÷ 2. Since 1 is smaller than 2, we use decimals, making it 10 divided by 2.

Step 4: 2 goes into 10 five times, giving us 0.5.

Step 5: Add the decimal result 0.5 to the whole number 1, resulting in 1.5. The answer for 1 1/2 as a decimal is 1.5.
