Question

Cai had 68 out of 82 in his art test. express this as a percentage

Answer 1

Answer: 82.93%

Explanation:

write a proportion

68/82=x/100

(Why x/100, because in a test the highest you can get is a 100%)

cross multiply

6800=82x

( 68(100) = 82(x))

Isolate the variable

6800/82≈ 82.93 (rounded)
