Skills Reciprocal

Friday, May 8, 2009
For our skills post we had to look up the word Reciprocal. Reciprocal means; A number related to another in such a way that when its multiplied their product is one or you can called it Multiplicative Inverse.

We can use this and other techniques to get answers to our questions.
Here is an example:

Now I'll show you 3 ways I can do 3/4 divided by 3/5. First I'll show you with a ratio table

You can also estimate your answer so you know roughly where its around. Ask yourself how many groups of 3/4's are in 3/5's? Less than 1 or more than 1. Its less than one.

And heres an example of reciprocal.
