Your chance of winning a game is 4 out of 7. If you play the game 111 times, how many times would you expect to win?

Round to the nearest whole number

63

Step-by-step explanation:

Using cross multiplication, you can set up this equation:

You will get 444 = 7x, then divide each side by 7 to get a decimal. Rounded to the nearest whole-number, is 63.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
