1) Three posters cost $ 9.60. At that rate, how many posters can you buy for $ 48?

Let x be how many posters can be bought with $48
Steps, Word Ratio, Ratio Table

Poster| $
    3    | 9.60                                                     9.60x = 3
     x   | 48                                                        9.60x = 144
                                                                        9.60       9.60
                                                                         x = 15
                                                


I can buy 15 posters with $48.




2) You estimate that you can do 12 math problems in 45 minutes. How long should it take you to do 20 math problems?


Let x be the minutes it should take me to do 20 math problems
Steps Word Ratio, Ratio Table

     45     |    12                                                     12x = 45
      x      |     20                                                    12x = 900
                                                                            12       12
                                                                           x = 75
   

It should take me 75 minutes for me to do 20 math problems
