Answer 1

25%

Explanation:

Of the 12 girls and 16 boys in Mr. Johnson's class, 3 girls and 4 boys wear glasses. You want to know the percentage of students in the class who wear glasses.

Percentage

The percentage is the fraction multiplied by 100%. The fraction is the ratio of glasses-wearers to total students.

percentage = (girls w/ glasses + boys w/ glasses)/(girls + boys)×100%

percentage = (3 +4)/(12+16) × 100% = 7/28 × 100% = 25%

25% of the students in Mr. Johnson's class wear glasses.
