Question

18x over 45 how would u simplify that

Answer 1

18x/45. factor 18 and 45 and cross out all the numbers that are the same.

18 = (2)(9) = (2)(3)(3)
45 = (3)(15) = (3)(3)(5)

they have (3)(3)/(3)(3) in common so get rid of them because they simply equal the number 1.

we are left with:

(2)x/(5) = 2x/5
