Answer:

25

Step-by-step explanation:

2.5 =10%

2.5*4= 10

2.5*6=15

Answer:

25

Step-by-step explanation:

Using P=(%)w we can substitute the values. First, I will define the variables. P = part (is), % = percent, w = whole (of)

10 = (40%)w

The reason for this is because 10 is a PART and 40% is a PERCENT and we are solving for the unknown WHOLE. We now divide 10 by 0.40 because to convert a percent to a decimal you just move the point two places to the left:)

10 divided by 0.4 = 25. So, there is a total of 25 students in Mr. Lee's class. Now, we can check this by multiplying 25 and 0.4 to get 10! It is in fact correct.
