78 as a Decimal
It is a simple question of decimal representation. Firstly, we need to understand whole numbers and decimals. Whole numbers are numbers without fractions or decimals. In contrast, decimals represent numbers that are not whole, using a decimal point (.) to separate the whole number part from the fractional part. The numbers to the left of the decimal point represent the whole part, while those to the right represent the fractional part.
What is 78 as a decimal?
Answer
78 as a decimal is written as 78.0. It is a terminating decimal, which means it does not repeat infinitely.

Step 1: Identify the whole number, which in this case is 78.
Step 2: Add a decimal point and a zero to show that there is no fractional part.
Therefore, 78 can be represented as 78.0, a terminating decimal with no repeating digits.
