Question 215108
How do I reduce this to simplest terms? 7m/2m+14 . 3m+21/9m
------------------------
General Rule: To reduce a fraction you must find one or more FACTORS
that are common to the numerator and the denominator.
-----------------------
Your Problems:
7m/2m+14 
You need to factor the denominator to get:
7m/(2(m+7))
---
There is no factor common to the numerator and the denominator
so you cannot reduce the fraction.
===========================================
3m+21/9m
You need to factor the numerator to get:
(3(m+7))/9m
A factor that is common to the numerator and denominator is "3".
Cancel the 3 that is common to get
= (m+7)/3m
That is as far as you can go.
