You can put this solution on YOUR website! 3 5/6 - 1 1/4 + 1 1/2
===========
Change to "improper fractions."
= (23/6) - (5/4) + (3/2)
You might spot the the LCD (Least Commom Denominator) is 12.
You might not.
-----------
The product of the DENs always works.
6*4*2 = 48
---
(23/6) - (5/4) + (3/2) = (184/48) - 60/48) + (72/48)
= (184 - 60 + 72)/48
= 196/48
Then reducing is easy.
= 49/12
========================
You can use the product of the DEN's, then, if it's asked for, the result is in the LCD.
-----
Wasting time and fretting about the LCD accomplishes nothing.
Using the product ALWAYS works, and reducing is easy.
You can put this solution on YOUR website! The least common multiple factor among 6,4, and 2 is 12.
3 (10/12) - 1 (3/12) + 1 (6/12)
= 3-1+1 ((10-3+6)/12))
= 3 (13/12)
=4 (1/12)
