Aloha, thanks for using Brainly.
Step-by-step explanation:
For 1. 7/8 is 90 percent so .90
For 2+. Add the bottom together, whatever you get divide top by bottom.
The others you just divide them by each other.
Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92
