In a stem plot the numbers on the left side of the line are called the stem and the value on the right side are called the leaves. The stem represents the tens place while the leaves represent the ones place of a number.
The scores of the students are as follows:
43 45 46
51 52 53 55 57
60 63 63 65 66 67 67 69 69
71 71 72 74 76 77 79

#SPJ1
1/3+2/5+4/3+3/5=8/3
Steps
A double negative makes a positive.
So, change all double negatives to positives (to simplify it)
1/3 + 2/5 + 1+1/3 + 3/5
What's the least common denominator here?
Yes, it is 15!
Change the fractions to that denominator
5/15 + 6/15 + 1+5/15 + 9/15
change 1+5/15 to 20/15, then add the fractions
Result: 40/15
Divide numerator and denominator both by the greatest common factor:5
8/3
