From the graph: there are 200 students overall. For the next 100, we can divide each number by 2 to find an estimate for how many with participate in MATH tutoring. 40 divided by 2 =20 students participating in MATH tutoring.

Part B- There are currently 55 students out of 200 in SCIENCE tutoring. We add 55 more for 400 = 110, add 55 more for 600=165, and then add half of 55 (27.5 or 28 because you CANNOT have half a student) for 700 students total. 55+55+55+28=193 students.

If the calculated test statistic is 2.148 when the critical value is 2.348, should you reject or not reject the null hypothesis,
Lisa [10]
The approach of critical value is used to determine likely or unlikely through determination whether observed test statistics is more than it would have been if null hypothesis was true. In other words, test statistics is compared to critical value and decision made.
If test statistics is more than critical value, the null hypothesis is rejected. Otherwise, null hypothesis is not rejected.

In the current scenario, test statistics (2.148) is less than critical value (2.348) and thus null hypothesis is not rejected.

I need to model 2 equivalent fractions for 6 fifths

Six fifths = \frac{6}{5}.
You can multiply the numerator and denominator by any number to find an equivalent fraction. 
Two examples of equivalent fractions would be \frac{12}{10} and \frac{18}{15}.
Hope that helped you.
