Adding fractions with unlike denominators ?

Mathematics

The fractions you start with have to be re-written with the same (common) denominator.

For example, if you were asked to add 3/5 and 6/7, you would:

1) Identify the Lowest Common Denominator (LCD):  Here it is 5*7 = 35.

2) Multiply both numerator and denom. of 3/5 by 7:  21/35

3) Mult. both num. and denom. of 6/7 by 5:  30/35

4) Combine these two equivalent fractions:   21/35 + 30/35 = 51/35 (answer)

 Try a few such problems yourself and write back if you need further help.

In how many ways can you choose 2 side dishes out of 8
Alina [70]
The first choice can be any one of the 8 side dishes.
               For each of these . . .
The 2nd choice can be any one of the remaining 7.

     Total number of ways to pick 2 out of 8 = (8 x 7) = 56 ways .

BUT ...

That doesn't mean you can get 56 different sets of 2 side dishes.

For each different pair, there are 2 ways to choose them . . .
(first A then B), and (first B then A).  Either way, you wind up with (A and B).

So yes, there are 56 different 'WAYS' to choose 2 out of 8.
But there are only 28 different possible results, and 2 'ways'
to get each result.
