Answer:

11 1/9 or 100/9 and 11.1%

Step-by-step explanation:

A circle has 360 degrees and that can be set equal to 100 percent. Since losing a turn is 40 out of 360 degrees that is equal to x over 100, x being percent of losing a turn. You set the fractions equal to each other and cross multiply to get 4,000 = 360x. From there you divide both sides by 360 to get 11.1 repeating which you round to 11.1%. 11.1 as a fraction is 11 1/9 or 100/9.

First multiply each term by 24(the common denominator found by 8×3) to remove the fractions and make things easier.
$24(5) + 24( \frac{x - 2}{3} ) = 24( \frac{x + 3}{8} )$
This will give you,
$120 + 8(x - 2) = 3(x + 3)$
Then just continue to simplify and isolate the variable.
$120 + 8x - 16 = 3x + 9$
$8x + 104 = 3x + 9$
$5x = - 95$
$x = - 19$
