    Simplifying a Rational Expression

    I have no clue how to answer this, can someone please run me through it?

    a) 1+4b/2a - 3/4a + 3 (subtraction)
    b) 2 - 1/2n + 3+m/mn (addition)

    You need to put paranthesis.
    Otherwise you are not going to get answered.

    Note if you have,
    \frac{1+x}{y}
    Then you do not write,
    1+x/y.
    Rather you must write,
    (1+x)/y
    That says which is untop.

    Oh, sorry.

    Ok, here it is.

    (1+4b)/2a - (3)/4a +3

    and

    2 - (1)/2n + (3+m)/mn
