Question 148559
Add,First Finding the LCD 
3/25+2/105+2/625
--------------------
The LCD is 625
-------------------
Rewrite each fraction with the LCD as its denominator:
(3*25/LCD) + (2*5/LCD) + (2/LCD)

-------------
The denominators are all the same so add the numberators:
[75 + 10 + 2]/LCD

= 87/625
