how do you convert units within a measurement system


Sagot :

You will have to write a proportion. Then use common denominators to write equivalent ratios. For example;

What is the weight of a 3 Ib human brain in ounces?
Use a proportion to convert 3 Ibs to oz.

16 ounces ? oz
————— = —————
1pound 3 pounds


Use common denominators to write equivalent ratios.


16•3 ?
----- = --- 3 is a common denominator.
1•3 3

48 ?
--- = ---
3 3

Equivalent rates with the same denominators have the same nominators.

?= 48

The weight is 48 ounces.
