Awill states that 9/10 of an estate is to be divided among relatives. of the remaining estate, 1/4 goes to the american cancer society. what fraction of the estate goes to the american cancer society?

9/10 of the estate goes to relatives.
There is only 1/10 of the estate left.
We can figure out how much 1/4 of 1/10 is when compared to the entire estate by multiplying those fractions.
1/4*1/10
1*1=1
4*10=40
1/40 of the estate would go to the American Cancer Society.

Hope this helps!
