7、s. Raise your hand when you are complete so your teacher can check your solutions.,Units which are larger than the basic units,There are also units which are larger than the basic units: 10 of the basic unit put together are called a decameter, decagram, or decaliter. To remember this think of a dec

8、ade. A decade is 10 years, while a “decaunit” has 10 units put together. 100 of the basic unit put together are called a hectometer, hectogram, or a hectoliter. 1,000 of the basic unit put together are called a kilometer, kilogram, or a kiloliter.,Moving from a larger unit to a smaller unit you must
