The sum of a number and 2/5 (two fifths) of itself is 56. What is the number?
HOW IN THE HECK AM I SUPPOSED TO SET UP THIS EQUATION? PLEASE HELP... I AM DESPERATE!

Try:
56 = n + 2/5n 
Thanks :) but now I'm stuck on actually finding out what the integers are :(

What is your problem with solving the equation?

I just don't know how to go about it.
I have
n + 2/5n = 56
but now what? 
n + (2/5)n = 56
The simple way is to convert 2/5 to a decimal. You can divide 2 by 5 on your calculator and obtain 0.4, then
n + 0.4n = 56
1n + 0.4n = 56
1.4n = 56
divide both sides by 1.4
1.4n/1.4 = 56/1.4
n = ?? 
56 = 1n +(2/5)n
56 = (1+(2/5))n
56 = (7/5)n
n = (5/7)*56
n= 40

THANK YOU SO MUCH! now it makes sense!!!!!!!!!!!!!!!!!!!!!!!!!
