Answer
6.4
Work Step by Step
We first only consider the fraction. In order to write a fraction as a decimal, we create a denominator of 100, if possible. Thus, we multiply 2/5 by 20/20 to get that the fraction is the same as 40/100. Anything divided by 100 equals that number with the decimal moved two to the left, so we know that this fraction in decimal form is .4. We add back the 6 to get an answer of 6.4.
