Step-by-step explanation:
Simplify each expression to lowest terms. Equivalent expressions will be any expressions which are equal after simplifying to lowest terms.
A. -1/9 * 6 = -6/9 = -2/3
B. -15/10 = -3/2
C. 12/-18 = -2/3
D. -3/4 * 2/1 = -6/4 = -3/2
E. -8/9 * 3/4 = -24/36 = -2/3

Answer:
Of the 777 rounds of the game in about 368 the ball will land in a red slot.
Step-by-step explanation:
Since a roulette wheel has 383838 slots, of which 181818 are red, 181818 are black, and 222 are green, and in each round of the game, a ball is tossed in the spinning wheel and lands in a random slot, supposing we watch 777 rounds of this game, to determine the approximate number of rounds where the ball lands in a red slot, the following calculation must be performed:
383838 = 100
181818 = X
181818 x 100/383838 = X
18,181,800 / 383838 = X
47.3684 = X
100 = 777
47.3684 = X
47.3684 x 777/100 = X
36,805.24 / 100 = X
368.05 = X
Therefore, of the 777 rounds of the game in about 368 the ball will land in a red slot.
