Determine who will be “x” and who will be “o.” 3. The “x” person will solve the first problem, and then have the “o” person check it. If it was solved accurately, then the player gets to take a turn on the board. If not, the player loses a turn. 4. Then the “o” person will solve the next problem, have the “x” person check it, and take a turn. If the player does not solve it correctly, that player loses a turn. In your own words… In your own words, write the steps for dividing a fraction by a fraction. What do you do when you have a mixed number divided by a fraction? Or a mixed number divided by a mixed number?
