In a class, 55% of the students are boys. 60% of the boys and 80% of the girls love singing. What is the percentage of students who love singing?%

Sure, let's break it down:

1. First, let's find out the percentage of boys and girls in the class. According to the problem, 55% of the students are boys. Therefore, the remaining 45% must be girls.

2. Next, we need to find out how many boys and girls love singing. 60% of the boys love singing, so we multiply 55 (the percentage of boys) by 0.60 to get 33%. Similarly, 80% of the girls love singing, so we multiply 45 (the percentage of girls) by 0.80 to get 36%.

3. Finally, we add the percentage of boys and girls who love singing to find the total percentage of students who love singing. So, 33% (boys who love singing) + 36% (girls who love singing) = 69%.

Therefore, 69% of the students in the class love singing.
