Hey there!
To solve this problem, first turn the mixed numbers to improper fractions then multiply 2 2/3 and 1 1/4 . . .
2 2/3 = 8/3
1 1/4 = 5/4
8 x 5 = 40
3 x 4 = 12
= 40/12
Simplify 40/12 . . .
40/12 = 3 1/3 <--------
The answer to your question is option B.
The bananas weighed 3 1/3 pounds.
Hope this helps you.
Have a great day!
Put numbers in order: 4,5,6,6,7,8,9,9,10,10,12,12,14,15
Cut the list into two equal parts: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Find middle numbers: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Lower quartile: 6
Upper quartile: 12
The difference of the values of the first and third quartiles of the data set is 12 - 6 = 6
