To convert the mixed number 2 5 into a decimal, we first need to understand its components. The number consists of a whole number (2) and a fraction (5), which is equivalent to 5/1.
First, we convert the fraction part (5) to decimal. Since it is a whole number, 5 remains as 5. Next, we add the whole number part (2) to this decimal number.
So, 2 (the whole number) + 5 (the decimal form of the fraction) equals 7. Thus, 2 5 as a decimal is 7.0.
