An algebraic way of turning a mixed number into a fraction is (as described in your question): a b/c = (ac + b)/c

This works because ac/c = a (the c will cancel itself out.) just like how 50/50 = 1, and (5*15)/5 = 15. You're basically multiplying a by c/c, which is 1.

When you add fractions with the same denominator, you simply add the numerators together.

Thus, a b/c = ac/c + b/c = (ac + b)/c

Q: When rewriting a mixed number as a fraction why do you multiply the who number by the denominator of the fraction?

You get the square of the the number.

You will get an equivalent fraction. However, if the numerator and the denominator of a fraction by zero, the result is not defined.

Multiply the numerator and the denominator by the same integer.

If you wish to multiply a fraction (numerator and denominator) by a number, you multiply the numerator by the number and leave the denominator as it was. For example, 2/3 * 4 = 8/3

Take the fraction you have, and multiply the numerator and denominator by the same number.
