Find a number that both of the denominates make the same number for example if one denominator is 1/7 and the other is 2/6 then you
2/6 * 7 = 14 over 42 then the other one would be 1/7 *6 which would be 6 over 42 you find common denominators by finding a number both of the bottom ones can equal. hope this helps
Leave the whole number alone for now. Divide 41 by 80 and you get 0.5125
So your answer is 9.5125
The answer to this is true

A = 47900
i = 5% = .05
n = number of compounding periods in a year (1,2,12,365)
t = number of years = 5
Combine (subtract) 3n and 2n to get 1n or n. Then you have n -5n =10n add 5n to 10n to get 15n. divide the 15 from n and your answer is n=15
