You should be able to answer this by glancing at it.  But if you can't,
then you have to set up an equation. 

Call the unknown number ' Z '.

You said that  0.4 = 10 Z

Divide each side of the equation by  10 :    Z = 0.4 / 10  = 0.04

Answer:

0.04

Step-by-step explanation:

0.4 is 10 times as much  as ? for answering this, we put x an unknown number such that 0.4 is 10 times as much  as x, so it does mean 0.4 =10x, so for finding the value of x, we divids 0.4 by 10, x= 0.4/10=0.04. the answer is 0.4 is 10 times as much  as 0.04Hope this helps.
