So first you multiply 8 over 11 and n and you get: 8/11n then you multiply 8 over 11 and 10 and you get 80 over 11 but then you have to make it a mixed fraction which is 7 1 over 2. then you end up with this equation: 8 over 11n X 7 1 over 2 equals 64. Then im stuck.. because im in 8th grade and in Pre Algebra so im just now learning this.. xD but maybe you can get it from there.
maybee if you woudl actually type the problem down instead of screenshotting it some people may actually be able to see it and actually answer the problem
