Corey needs 24 boards that are 47 1/2 inches long. how many feet of board should he buy?

An interesting way to think about this is to make use of the associative property of multiplication.

... 24 × 47 1/2 inches = (24 inches) × 47 1/2 . . . . associate inches with the other number

Now, you know that 24 inches is 2 feet, so you can finish the problem

... (2 feet) × (47 1/2) = (2×47 + 2×1/2) feet = 95 feet

Another way to think about this is

... 24 × 47 1/2 inches = 24 × (48 inches - 1/2 inch)

... = 24 × (4 feet - 1/2 inch)

... = 96 feet - 24×1/2 inch

.. = 96 feet - 12 inch

... = 95 feet

The straightforward way to do this is to find the total number of inches, then convert that to feet.

... 24 × 47 1/2 inches = 24×47.5 inches = 1140 inches

Multiplying by the units conversion factor (1 ft)/(12 inches), we get

... (1140 in)×(1 ft)/(12 in) = 95 ft

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

first one because it can't have a fraction in it
