In this problem, the hardest part is being able to solve it without using a calculator. Decimals and fractions are always confusing. Doing this with the calculator is easier because we can use the math frac button and that's it, but that is not the point of this problem. Here we have to be able to keep working with the fractions and then end with a fraction. The other tricky part of this problem is that we might forget that we have an integer. At the end of the problem we have to plug it into the answer but still keep it as a decimal.
