a bycicle tire completes 9/10 of a revolution every 1/3 of a second. how many revolutions will the tire complete every minute?

162 RPM

Step-by-step explanation:

Start by multiplying 9⁄10 by the Multiplicative Inverse of ⅓, which is 3:

9⁄10 : ⅓ → 9⁄10 * 3 = 2 7⁄10

After this, multiply the result by sixty seconds, since there are sixty seconds in one minute:

60 * 2 7⁄10 = 162

So, it will make 162 RPM.
