3 2/5 as a Decimal
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.
