Basic Fraction Algebra

Trying to help my little brother through this particular problem but im stumped. In the book it says the correct answer is , ive gone through all the rest of his example problems but have been able to solve them successfully.



LCD
15



Thanks

10 * 2x = 20x
3 * 15 = 45

When facing a multiplication of two fractions, you can simply multiply both numerators together and both denominators together. You'll end up having one fraction, that you can eventually simplify. :)

20x/45 = 4x/9

Thanks! And I cant believe I glossed over that. I suppose thats what happens when you get off a double shift.

As I always said, simple things can sometimes be harder than the tough ones. And I have proven this, with life experiments. :p
