Expert Answer

Fractions are just a form of division—it's the same thing. 3/4 is the same thing as 3 divided by 4.

Question

What is 14 2/3 + 8 5/7 as a mixed number?

Community Answer

(14 2/3) + (8 5/7) = (44/3) + (61/7). The common denominator is (3)(7) = 21. So the fractions become (308/21) + (183/21) = 491/21 = 23 8/21.

Community Answer

On most calculators you aren't allowed to convert to a fraction. You first have to convert to a decimal and then know how to convert a decimal to a fraction.
