Question 93408
 2/5w + 10 - 3/2w - 4  First, we will multiply each term by the LCD, 10w, and this will give us a common denominator

{{{(2/5w)(10w/10w)+10(10w/10w)-(3/2w)(10w/10w)-4(10w/10w)}}}

simplifying, we get:

{{{4/10w+100w/10w-15/10w-40w/10w}}} Now we can re-write this as follows:

{{{(4+100w-15-40w)/10w}}}  Next we collect like terms in numerator

{{{(60w-11)/10w}}}-----------------ans
