Question

3. Seventy-six percent of the brass instruments in the band leading the

parade were trombones. If there were 100 brass instruments, how many
were trombones?​

Answer 1

Answer: 76 trombones

Step-by-step explanation: The first thing to recognize is that 76% is out of 100%. So, in other terms, you can say that 76/100 is equal to the percentage given to us. If we know that, we can set up a ratio problem.

`(76)/(100) = (x)/(100)`

Here, you can cross multiply. (76x100) = (100xX) To make things simple, divide both sides by 100. In the end, you will get X = 76 trombones.
