Question

A school assembly had 600 students in attendance, and 35% of them were first-graders. How many first-graders were at the assembly?
can u also list the formula on how to do this while ur at it pls and ty

Answer 1

Answer:

210 kids

Step-by-step explanation:

So the formula is basically part over whole is equal to x/100%

So for here it would be x/600 = 35/100

Solve that and you will get 210

Answer 2

Answer:

210 Were First Graders

Step-by-step explanation:

35 percent of 600 is the same as 35 per hundred of 600. We can therefore make the following equation:

35/100 = X/600

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

35/100 = X/600

X/600 = 35/100

X*600/600 = 35*600/100

X = 21000/100

X = 210

The work above shows the long way to explain how to calculate 35 percent of 600 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 35 percent of 600?", Y is 600 and P is 35:

(600 * 35)/100 = 210

And once again you see that the answer is 210.
