If kevin makes c toys in m minutes, how many toys can he make per hour
mina [271]

Answer:

\frac{60c}{m}

Step-by-step explanation:

We can use the unity rule to solve this problem.

Number of toys made in m minutes = c

Number of toys made in 1 minute = \frac{c}{m}

Number of toys made in 60 minutes = \frac{c}{m} \times 60 = \frac{60c}{m}

Since 60 minutes = 1 hours, we can write:

Number of toys made in 1 hour = \frac{60c}{m}

Therefore, we can say that Kevin makes \frac{60c}{m} toys per an hour.
