Answer:
1. 3 students
2. 1/10
Explanation:
if there are 30 kids in the class, and 2/5 are in band that means 12 students are in band
30÷5 =6
6×2= 12
if 1/4 of those 12 play the saxophone, then 3 of those students play the saxophone.
12÷4= 3
3 is 1/10 of 30, which gives you the answer to the second question.
