40x = 4

x = 4/40

x = 1/10

x = 0.1

So 10% of 40 is 4.

Percent mean " per one-hundred "
Another way to ask this question is
" Express +4%2F40+ as a percent "
+x%2F100+=+4%2F40+
+x%2F100+=+1%2F10+
+x%2F100+=+10%2F100+
+x+=+10+
10% of 40 is 4

Hello,
I'll give you a hint---some words in math have special meanings.
"of" means multiply
"is" means equal
What percent of 40 is 4?
We can write this as:
percent times 40 equals 4
p (40)=4
Divide both sides by 40 to get:
p=.10
or
10%
Make sense?
