The table shows the number of students who wear hats in three Primary 1 classes in a school.
- How many students in the three classes do not wear hats?
- The total number of students who wear hats is the same as the total number of students in Class 1C. How many students in Class 1A wear hats?
(a)
Total number of students not wearing hats
= 15 + 13 + 27
= 55
(b)
Total number of students in Class 1C
= 27 + 7
= 34
Number of students wearing hats in Class 1A
= 34 - (11 + 7)
= 34 - 18
= 16
Answer(s): (a) 55; (b) 16
