You made a deal with Ms.Williams to read 100 pages every night. You know that it takes you 32 minutes to read 16 pages. How long
AnnyKZ [126]
Put the problem into a proportion to make it easier to solve.

32        x
      =
16       100

You can use cross products to simplify this proportion.  Multiply 32 by 100, and set that number equal to 16 *x.  

Your equation should now look like this
3200=16x

You are trying to get the variable alone on one side, so you should divide both sides by 16.

If this is performed correctly, then your final answer should be 

x=200.

It will take you 200 minutes (3 hours 20 mins) to read the pages that you promised Ms. Williams
