To figure out percetages on tests, divide the number of questions answered correctly by the total number of questions. 

66 ÷ 78 = 0.85

Next, move the decimal point over two places.

0.85 = 85%

Shawn got 85% on the science test. 

Hi there! ;) The answer to your question is 0.85 or 85%. I got the answer because I divided 66/78(66 divided by 78) which equals 0.845 but I rounded it because 5,6,7,8,9 means round up.

Hope I helped! :D
