80 2/5 as a Decimal
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: the numerator (number on the top), here, 2 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 5. 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 80 2/5 as a decimal?
Answer
80 2/5 in decimals can be written as 80.4. It is a terminating decimal, which means it does not repeat infinitely.
Explanation
To convert 80 2/5 into a decimal, we need to consider both the whole number and the fractional part separately. Let's see the step-by-step breakdown of the process:
Step 1: Identify the whole number, which is 80, and the fraction, which is 2/5.
Step 2: Convert the fraction 2/5 into a decimal. Divide the numerator (2) by the denominator (5).
Step 3: As 2 is smaller than 5, we use the decimal method. Add a decimal point and a zero to the dividend, making it 20.
Step 4: Divide 20 by 5, which equals 4. Place 4 in the decimal part. Step 5: Combine the whole number and the decimal obtained from the fraction.
The result is 80.4. Thus, 80 2/5 as a decimal is 80.4.
