There are 550 people at the school carnival. Part A
If 385 of the people are students, what percentage of the people at the carnival are students?

Part B:
If 30% of all the people at the carnival are on a ride, how many people are on the ride?

I don’t know the answer I just need some points to ask more questions

Step-by-step explanation:

70% of the people at the fair are students

165 people are on the ride

Step-by-step explanation:

In order to find a percentage, take the fraction given, 385/550, and divide the numerator, 385, and divide it by the denominator, 550. Once completing this, we get 0.7

Next, we multiply the result by 100, and get 70, thus, 385 is 70% of 550.

To find how many people 30% of 550 is, we take the percentage and put it in a fraction with the denominator being 100(changes with size of fraction like a decimal, 300 would be over a denominator of 1000)

With 30/100, we then multiply by 550 with the equation looking like this:

30/100*550/1

Once we finish multiplying(typically using a calculator, although you can do it manually) we get 165, the value of how many people are on rides out of the total 550.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
