1 4/5 as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn mixed numbers and decimals. A mixed number has a whole number and a fractional part. The fraction represents a part of the whole, consisting of a numerator (the number on the top) and a denominator (the number below). A decimal is a way to represent a number that is not whole, 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, and those to the right represent the fractional part.
