The decimal form of 6 and 1/2 is 6.5.
To understand this, first, we need to break it down. The number 6 is a whole number, and 1/2 is a fractional part. In decimal form, 1/2 translates to 0.5. Therefore, when we add these two parts together—6 (the whole number) and 0.5 (the decimal representation of 1/2)—we get:
6 + 0.5 = 6.5
So, in conclusion, 6 and 1/2 expressed as a decimal is 6.5.
