Best ResponseYou've already chosen the best response.0Being by isolating the variable, to do this we divide both sides of the equation by 5/4. Remember that dividing a fraction by another fraction is really multiplying the first fraction by the reciprocal of the dividing fraction. \[(a  8) = \frac{ 2 }{ 3 } \times \frac{ 4 }{ 5 }\] We get\[a  8 = \frac{ 8 }{ 15 }\] Now you add 8 to both sides to get a on it's own..\[a = \frac{ 8 }{ 15 } +8\] Now we need a common denominator to add these fractions, so..\[a = \frac{ 8 }{ 15 } +\frac{ 120 }{ 15 }\] Now we have \[a = \frac{ 128 }{ 15 }\]

Best ResponseYou've already chosen the best response.0No, factors of 15 are 3,5, and 128 is not divisible by either one.

Best ResponseYou've already chosen the best response.0Well look at the factors of 15, there's 1, 3, 5 and 15. 128 isn't divisible by any of those, so it can't be simplified. If you want it in mixed number it's:\[8\frac{ 8 }{ 15 }\]
