Find the lcd of the fractions, and then simplify the expression. assume that no denominator equals zero. 5/(3x^2y) - 4/(6xy^3
show all the steps so you can me understand (:

We can simplify second fratction by divide 2
4/2=2
6/2=3
2/(3xy^3)
common denomenator
factor
3x^2y=3*x*x*y
3xy^2=3*x*y*y
LCD=3*x*x*y*y=3x^3y^2

multiply first fraction by y/y and second fraction by x/x
(5y)/(3x^2y^2)-(2x)/(3x^2y^2)=
(5y-2x)/(3x^2y^2)

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
