Eight out of 21 instruments in the band are woodwinds. If there are 63 instruments in the band, how many more are not woodwinds
Zepler [3.9K]

I don't think you need to do anything special for this question. But do be careful how you read it.

Total number of instruments = 63

Number of woodwinds = 21

Number of non woodwinds = 63 - 21 = 42 non woodwinds.

What you have to be careful about is that this is not the answer.

It says how many more .... So now you have to do another subtraction.

Total number more = Number of non woodwinds - woodwinds.

Total number more = 42 - 21

Total number more = 21 <<<< Answer

I believe it is neither

For one if you plug in either of them the first one is going to be negative 3. But if you use the second one then your answer would be -3+12= -10 but -3+12 is 9 so I would go with neither because I don't see how it's both
