The ratio of the diameter of ball A to the diameter of ball B is 8/ 17 when measured in millimeters.
To compare the diameters of ball A and ball B, we need to make sure they are in the same unit. Let's convert the diameter of ball B from centimeters to millimeters:
1 cm = 10 mm
So, the diameter of ball B in millimeters is:
Diameter of ball B in mm=6.8cm×10mm/cm=68mm
Now, we can find the ratio of the diameter of ball A to ball B:
Ratio= Diameter of ball A/ Diameter of ball B
Substitute the values:
Ratio = 32 mm/ 68mm
Now, simplify the fraction:
Ratio = 8/ 17
So, the ratio of the diameter of ball A to the diameter of ball B is
8/ 17 when measured in millimeters.
