    If you just make an equation you can solve this really easily.

    One fifth a number (number being A) plus three of that number = 32

    A/5 + 3A = 32
    A + 15A = 32*5
    16A = 32*5
    16A = 160
    A = 10

    Check to make sure(not absolutely necessary but at least you know your right)
    10/5 + 3(10) = 32
    2+ 30 = 32
    32=32

    Q2

    A + 2A/3 = 35
    3A + 2A = 35*3
    5A = 105
    A = 105/5 ---> A = 21 !

    To solve these kinds of problems just make "a Number" equal a variable then you can write out the equation and solve.
