How many 45 minute games can be played in 6 hours? 1 game * 1 game * 1 game * 1 game * 1 game * 1 game * 6 games + 2 more

What is happening in our equation??????? When we multiply 6 x 4, we are finding how many fourths are in 6 hours. There are 24 fourths in 6 hours. The 24 that we have is now divided into groups of 3. Twenty four sections divided by 3 gives us our 8 games.
