90 as a Decimal
This is a simple question about decimal representation. To understand this, we need to learn about whole numbers and decimals. A whole number is a complete entity without any fractional or decimal component. A decimal, on the other hand, is a way to represent numbers that are 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 part, and those to the right represent the fractional part.
