To solve for this, first multiply 7/8 by 4/7 to find the height of the koala, which is needed to find the height of the penguin. This would get you to the answer 28/56 if you multiply straight across. However, it would be more difficult to multiply with an unsimplified fraction so you would try to simply 28/56 by dividing the numerator and denominator by its greatest common factor, 28. This would result in 1/2. Now that you have the height of the koala, you can use its height to find the height of the penguin. To do this, multiply 1/2 by 7/8 which will lead to your answer, 7/16 meters.
