Answer:
C, 2 1/2
Step-by-step explanation:
First, you’d cross out the 3 and the 6, simplifying the problem to 1*5/2, then you’d multiply across. This should give you 5/2, which simplifies to 2 1/2
3*5/6 = 5/2 = 2 1/2
I hope this helps!

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.
