Write as a decimel. 8 out of 10.

Question

this is my daughters fourth grade homework. the caption says " Write as a decimel. 1). 8 out of 10.

Answer 1

Think of it as dividing 8 by 10.  When you divide a number by 10ⁿ, you move the decimal point n places to the left on the base number.

 

So      8.0/10ⁿ  is 0.8
