There are 45 students who play a woodwind instrument in the school band. Of these, 18 play the saxophone. What percent of these
Mashutka [201]

Answer:

40% students play the saxophone.

Step-by-step explanation:

Given:

Total Number of students who play woodwind instrument = 45

Number of students who play saxophone = 18

We need to find the percent of students who play saxophone.

Solution:

To find the percent of students who play saxophone we will divide Number of students who play saxophone by Total Number of students who play woodwind instrument and the multiply by 100.

framing in equation form we get;

percent of students who play saxophone = \frac{18}{45}\times100= 40\%

Hence 40% students play the saxophone.
