Answer 1

Explanation:

`\displaystyle\\(10px^2)/(3c^2d) /(5px)/(6c^2d^2) =\\\\(10px^2)/(3c^2d)*(6c^2d^2)/(5px) =\\\\(60c^2d^2px^2)/(15c^2dpx^2) =\\\\4d\\\\\\(3)/(x+7) /(8x^2-8x)/(x^2+6x-7) =\\\\(3)/(x+7) /(8x(x-1))/(x^2-x+7x-7) =\\\\(3)/(x+7) /(8x(x-1))/(x(x-1)+7(x-1)) =\\\\(3)/(x+7) /(8x(x-1))/((x-1)(x+7)) =\\\\(3)/(x+7) /(8x)/(x+7) =\\\\(3)/(x+7) *(x+7)/(8x) \\\\(3(x+7))/(8x(x+7))=\\\\(3)/(8x)`
