Given:
The number of teeth = t = 25
The gear is driven by a 10-tooth driver gear (T) at 250 RPM
Let the speed = s
So, using the ratio and proportion
Solve for s:
So, the fear will be driven by 625 RP
There are a total of 2,000 students in the school.
1.) There are 540 students in the 6th grade. 540 is only 27% of students compared to the total. To find the total students in the whole school, we divide 540 by 27%.
2.) We first change 27% into a decimal by moving the point two times to the left. (Rule to change the percent into a decimal)
27% = .27
3.) Before we divide, we remove the decimal by moving the decimal two times to the right and so do we to 540.
.27 = 27
540. = 54000.
4.) Now we have 54000 divided by 27 which give us the answer of 2,000.
