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 represents how many parts out of the whole, and the denominator (number below) shows how many parts make the whole, here it is 5. A mixed number like 1 2/5 consists of a whole number and a fraction. 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.

What is 1 2/5 as a decimal?

Answer

1 2/5 in decimals can be written as 1.4. It is a terminating decimal.

Explanation

To convert 1 2/5 into a decimal, we need to convert the fraction part first. Let's see the step-by-step breakdown of the process:

Step 1: Identify the whole number and the fraction part. Here, the whole number is 1, and the fraction is 2/5.

Step 2: Convert the fraction 2/5 to a decimal by performing division.

Step 3: Divide 2 by 5. Since 2 is smaller than 5, we use the decimal method by adding a decimal point and a 0, making it 20.

Step 4: 5 goes into 20 four times, so 2/5 equals 0.4. Step 5: Add the whole number to the decimal part. Therefore, 1 + 0.4 = 1.4. The answer for 1 2/5 as a decimal is 1.4.
