66 over 90 and 143 over 195 show (in a video, an image, a slideshow, etc.) how you would determine whether the two fractions are equivalent. Remember, there are multiple methods you could use, so be sure to give reasons for your approach.

Respuesta :

Put both of the fractions equal to each other. 66/90 = 143/195. Then do cross multiplication. 66 x 195 = 90 x 143. If both sides come out equal then they are equivalent. If they do not equal each other, then they are not equivalent.
