Answer 1

1. Student #2, 81%

2. Student #2, 85%

Explanation:

1. Student #1:

(86 + 59 + 85 + 87 + 69) ÷ 5

= 386 ÷ 5

= 77.2

This student scored an average of 77.2%.

Student #2:

(81 + 96 + 79 + 64 + 85) ÷ 5

= 405 ÷ 5

= 81

This student scored an average of 81%.

Therefore, Student #2 has the better average.

2. Student #1:

(75 + 96 + 63) ÷ 3

= 234 ÷ 3

= 78

This student scored an average of 78%.

Student #2:

(83 + 72 + 100) ÷ 3

= 255 ÷ 3

= 85

This student scored an average of 85%.

Therefore, Student #2 has the better average.
