Paco's age divided by 3 is equal to 4. Let p represent Paco's age and write an equation to model the situation. Then solve the equation to find Paco's age.
An equation could be: p/3=4 To solve this equation: p/3*3/1=4*3/1 : p=12 : Paco is 12 years old--you are using what is called "Inverse Operation"!!! (otherwise you could multiply 3*4 to get 12 by reversing operations) I hope this helped you!
