Answer: 20:8 or 5:2
Step-by-step explanation: If the total number of games is 28, then you would subtract the number of games won from the total number of games played by the basketball team to find the number of games lost. That would give you the equation 28-20=8. Now that you have both the number of games won and lost, you can make your ratio, which is 20:8. If you need to round the ratio down (which you usually do), you divide both numbers by the Greatest Common Denominator. The Greatest Common Denominator is the largest number that both numbers in the ratio can be divided by. In this situation, that number is 4, meaning your final answer is 5:2.
