3 2/5 as a Decimal

Professor Greenline Explaining Math Concepts

This is a straightforward question on decimal conversion. To understand it, we must first learn about fractions and decimals. A fraction represents a part of a whole and consists of two parts: the numerator (the number on top), which shows how many parts of the whole are being considered, and the denominator (the number below), which shows how many parts make up the whole. A decimal is a way to represent a number that is not whole by 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 number, while those on the right represent the fractional part.

What is 3 2/5 as a decimal?

3 2/5 as a decimal

 

Answer

 

3 2/5 in decimal form is 3.4. It is a terminating decimal, meaning it does not repeat infinitely.

 

Explanation

 

To convert 3 2/5 to a decimal, we first convert the fractional part 2/5 to a decimal.

 

Step 1: Identify the numerator and denominator. Here, the numerator (2) will be the dividend and the denominator (5) will be the divisor.

 

Step 2: Divide the numerator by the denominator. Since 5 goes into 20 (which is 2.0) four times, 2 divided by 5 equals 0.4.

 

Step 3: Add the whole number part to the decimal obtained. Thus, 3 plus 0.4 equals 3.4.
