Question

Randy won 36 out of 54 games of tic tac toe. what percent of the games did he win

Answer 1

36/54 = x/100

54x = 100 * 36
54x = 3600
x = 3600 ÷ 54
x = 66.666666.... so 66.67

First put it into a proportion and then cross multiply. After that you divide both sides by 54 to get x alone which gives you 66.66666 which is rounded to 66.67

Answer: 66.67%

Answer 2

$\dfrac{36}{54}\cdot100\%=\dfrac{2}{3}\cdot100\%\approx66.7\%$
