How to use it?
Example question: If there are 3 boys for every 4 girls and there are 27 boys in the class, how many girls are there?
How to set up the ratio:
3 27
— = —
4 x
Solve it?
[Cross Multiply]
3x= 108
[Divide]
X= 36
How to check it?
Reduce 27/36 and see if it equals 3/4
OR
Plug both into the calculator and both should come out with the same decimal. In this case it is 0.75
So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.

Here is an image of a box and whisker plot, as you can see there are labels on it. The Smallest value can also be called the Minimum and the Greatest value can also be called the Maximum.
