Question

a dime weighs about 1/12 ounce. Jody has 1 pound ( 16 ounces) about how many dimes does she have

Answer 1

So if a dime weighs 1/12 of an ounce, then there are 12 dimes in 1 ounce, or 12 dimes/ounce.  If Jody has 16 ounces of dimes, then she has: 

 

12 dimes/ounce x 16 ounces = 192 dimes

 

Another way to look at it is from the units, we have dimes/ounces and ounces.  If we multiply 5/10 x 10, we get 5.  So if we multiply dimes/ounces x ounces, we get dimes.

 

Hope this helps.
