Answer: \(m=3f\)
Step-by-step explanation:
Given: Esther the Clown does face painting at the city carnival.
She paints 7 faces every 21 minutes.
So, the time taken by Esther to paint 1 Clown face =\(=\frac{\text{total minutes}}{\text{total faces}}=\frac{21}{7}=3\text{ minutes}\)
If 'f' represents the number of faces and 'm' represents the number of minutes, then the total time spent to make 'f' clown faces is given by :-
\(m=3f\)
