X GA.8.2
Write the ratio of the first measurement to the second measurement. Compare in millimeters.
diameter of ball A: 45 mm
diameter of ball B: 8.5 cm
The ratio of the diameter of ball A to the diameter of ball B is
(Type the ratio as a simplified fraction.)

Answer :

90/17


You would take 45/8.5, but that’s an improper fraction so you’d multiply top and bottom by two, resulting in 90/17. As far as I know, that fraction will not simplify down further. You could write it as a whole number with a fraction— 5 and 5/17 but I’d assume that’s not what they’re looking for
