2/5w + 10 - 3/2w - 4 First, we will multiply each term by the LCD, 10w, and this will give us a common denominator
%282%2F5w%29%2810w%2F10w%29%2B10%2810w%2F10w%29-%283%2F2w%29%2810w%2F10w%29-4%2810w%2F10w%29
simplifying, we get:
4%2F10w%2B100w%2F10w-15%2F10w-40w%2F10w Now we can re-write this as follows:
%284%2B100w-15-40w%29%2F10w Next we collect like terms in numerator
%2860w-11%29%2F10w-----------------ans
