Answer: Some fractions (1/4, 1/2, and 3/4) automatically switch to a fraction character when you type them (¼, ½, ¾). But others do not (1/3, 2/3, 1/5, etc.).
FOR EXAMPLE: What is the fraction of 1, 2, 1, 4, 1, and 8? Well...
Once again, we find that 1/2 + 1/4 + 1/8 = 7/8. Both methods yielded the same result, whether we add two fractions first and then add the last one to the result, or add all three together at once, the answer is the same.
