there are 40 students at Bali high who plays stringed instruments. of these, 1/4 play viola, 1/5 play cello, and the rest play violin. how many students play violin?

The answer that I got was 22 because 8+10=18 and 18+22= 40

Ah, music-loving students at Bali High! Let me do some quick calculations. We know that 1/4 of the students play viola and 1/5 play cello. So, if we add those fractions together, we get 9/20. To find out how many students play violin, we subtract this from the total number of string instrument players. Now, let's do some math:

40 students * 9/20 = 18 students.

So, 18 students play the violin. Remember, music is all about finding the right "strings" to play!

To find the number of students who play the violin, we will first calculate the number of students who play viola and cello.

Let's start with the viola. We know that 1/4 of the 40 students play the viola. To calculate this, we divide the total number of students by 4:

40 / 4 = 10 students play the viola.

Next, let's find out how many students play the cello. We know that 1/5 of the 40 students play the cello. To calculate this, we divide the total number of students by 5:

40 / 5 = 8 students play the cello.

Now, to find the number of students who play the violin, we subtract the number of students who play the viola and cello from the total number of students:

Total students - (Viola players + Cello players) = Violin players.
40 - (10 + 8) = 40 - 18 = 22 students play the violin.

Therefore, there are 22 students at Bali High who play the violin.

I don't know please help me

1/4 * 40 = 10

1/5 * 40 = 8
