I have a question and I have read and read and cant comprend how to figure the problem.
a girl has 1/5 of her portfolio in us stocks and 1/8 in euro stocks and 1/10 in japanese stocks the rest is in municipal bonds.
what percent is in muncipal bonds and what fraction is in mucipal bonds. I know I need to start with making the fractions the same but I am so confused

Let's first find the common denominators of the fractions.
1/5 = 8/40
1/8 = 5/40
1/10 = 4/40
The total for stocks is 17/40 of her portfolio.
40/40  17/40 = 23/40
To find the percentage, divide:
23/40 = ??
Then change that decimal to a percent. 
first find the common denominator. which is 40 so the fractions become 8/40 5/40 4/40. add them up and u get 17/40. then subtract 17/40 from 40/40 and you get 23/40 and that's your fraction. then divide 23 by 40 and you get 57.5% and that's your percent.

Thanks i was getting confused but you explained it well.
