The millers budget 1/2 of their income for fixed expenses and 1/8 of their income for savings. what fraction of their income is left?

To figure this out you must find a common denominator which is 8. one denominator is already 8 so you just have to multiply the other one to get 8. To do that just multiply the denominator so it will be 1/8, but when you multiply the denominator of a fraction to get a common denominator you have to multiply the numerator by the same number so the fraction will now be 4/8. Now you just have to add the two. 1/8 + 2/8 = 3/8 

You need to show me the graphs so that i can choose one
