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!

  • algebra 1 -

    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?

  • algebra 1 -

    I just don't know how to go about it.

    I have

    n + 2/5n = 56

    but now what?

  • algebra 1 -


    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
