The sum of two numbers is 70 the larger number is 4 more than twice the smaller number?
Call the large number L and the small number S.L + S = 70L = 4 + 2SSubstitute the value of L in the second equation into the first equation to get:4 + 3S = 703S = 66S = 22Plugging 22 in for S (in either equation) gives:L = 48
What is .323232 as a fraction?
You solve this as follows. You call your number "x", and write:x = .323232... (equation 1) Then you multiply this equation by 100 (a one, followed by two zeros - this is because the length of the period is 2), and get: 100x = 32.323232... (equation 2) Now you can subtract equation 1 from equation 2, and solve for "x". This will give you "x" as a fraction.
