1/2n - 1/4n = 10
2/4n - 1/4n = 10
1/4n = 10
4(1/4n) = 4(10)
n = 40

Word problems are the most difficult thing for anyone to get good at. I think it's commendable that you're hanging in there and trying:
"If I take a fourh of a number away from half the number, I get 10. What is the number?"
Let a number be: x
Take away means: -
Then a fourth of the number is:
half the number means:
I get means: =
The equation is:
The LCD is 4.

The number is 40.
You could clear the fractions by multiplying everything by four in the first step if you hate adding fractions.
Happy Calculating!!!

one fourth of one half is the same as saying (1/2)X-(1/4)X=10
to simplify the two terms you can simply subtract them as they are similar terms.
once simplified you ger 1/4x=10 divide by 1/4 to isolate x
x=40
