Well 21-8= 13 63-21=42 42-21=21 13*2=26 t There is 26 non woodwind instruments

Answer 2

Answer:

15 more are not woodwinds than woodwinds

Step-by-step explanation:

If there are 8woodwinds out of 21instruments, to know the number of woodwinds when we have 63instruments can be gotten as shown below;

8woodwinds = 21instruments

x woodwinds = 63instruments

Cross multiplying we will have;

x woodwinds × 21instruments = 8 woodwinds × 63instruments

x woodwinds = 8woodwimds × 63instruments/ 21instruments

x = 8×63/21

x = 24

This shows that there will be 24 woodwinds if there are 63 instruments

If there are 24woodwinds, number of those not woodwinds will be;

63-24 = 39

Therefore we have 24woodwinds and 39 that are not woodwinds.

To know how many more instruments that are not woodwinds than woodwinds, we will take the difference between those not woodwinds and those of woodwinds to give;

39-24 = 15

This shows 15 more are not woodwinds than woodwinds
