Understand Problem: Understand the problem and identify the given information.We know that Emperor penguins make up 30% of all the penguins at the zoo, and there are 15 Emperor penguins. We need to find the total number of penguins at the zoo.
Set Up Equation: Set up the equation to find the total number of penguins.Let the total number of penguins be represented by x. According to the problem, 30% of x is equal to 15.So, the equation is 0.30×x=15.
Solve Equation: Solve the equation for x.To find x, divide both sides of the equation by 0.30.x=0.3015
Perform Division: Perform the division to find the total number of penguins. x=0.3015x=50
Verify Solution: Verify the solution.If there are 50 penguins in total and 30% are Emperor penguins, then 30% of 50 should be 15.0.30×50=15This is true, so our solution is correct.
