Step-by-step explanation:
Assuming you mean flutes 5: clarinets 4: trumpets 3...
Question 1 Answer: There are <u>36 trumpets</u>
Question 1 Explanation: 60/5=12 (the amount it went up in ratio), then multiply 12 by each of the other ratios. If there are 60 flutes then there are 48 clarinets (4*12) and 36 trumpets (3*12). If you want to check work, you can then divide answer back by 12 and get the ratio again.
Assuming there are no other type of band instruments in Carver's band then...
Question 2 Answer:There are 50 flutes, <u>40 </u>clarinets, and 30 trumpets.
Question 2 Explanation: add the ratio then divide it by the number of band people (5+4+3=12: 120/12=10) this answer is then what you multiply for each ratio. So, flutes 5*10=50, clarinets 4*10=40, trumpets 3*10=30. 50+40+30=120. Therefore, if there are no other type of band instruments in Carver's band there are 40 people who play the clarinet (unless of course some are played by computers/robots or an amazing person can play multiple at a time.
