Note:

Many math textbooks will show answers as follows: your answer should always be in the form with which you started.

Example 1: if your problem begins with a mixed number, then your answer should be in a mixed number instead of a fraction.

Example 2: if your problem begins with a fractional exponent, then your answer should be with exponents instead of in radical form.

Example 3: if your problem begins with an radical, then your answer should be with a radical instead of in exponent form.

The exception to these three examples are when the problem reduces to a whole number.

Be careful not to put numbers in the numerator that shouldn't be there. 30 should indeed be the new denominator; you then have 1/2 = 15/30, 2/3 =20/30, and 3/5 =18/30. Adding the fractions, you get 53/30, or 1 & 23/30.

The whole numbers 22+15+18= 55. Add the 1 23/30, and the answer is 56 23/30
