Customary Conversions!

Today we began working with actual conversions in the Customary System!

What you need to know:

LENGTH:
1 foot = 12 inches
1 yard = 3 feet = 36 inches
1 mile = 1,760 yards = 5280 feet

MASS:
1 pound = 16 ounces
1 ton = 2000 pounds

LIQUID CAPACITY:
1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 2 cups
1 cup = 8 fluid ounces

As you know, today we used proportions to help us solve our homework problems.  Remember to set up the first fraction with what we already know using the labels from the problem...

ex:  4 ft = ______ in

12 inches
  1 foot

Then complete the set up by using what we want to know as part of the second fraction.

12 inches  --   ? inches
  1 foot     --     4 feet

Then use multiplication (or sometimes division) to help you solve the proportion

                x4

12 inches  --   ? inches
  1 foot     --     4 feet
               x4




                x4

12 inches  --  48 inches
  1 foot     --     4 feet
               x4





I hope that this helps!  We will get more practice in class tomorrow!!!!


Tonight's homework is both sides of the customary conversion worksheet.
