Answer 1

8.

The weights of the cartons of raspberries picked by the students are:

`(3)/(4),(1)/(4),(2)/(4),(4)/(4),(1)/(4),(1)/(4),(2)/(4),(3)/(4),(3)/(4)`

To complete the table, on the first column you have to write each observed weight, those are: 1/4, 2/4, 3/4, and 4/4

Then, on the second column, you have to write one tally, for each box that has the said weight.

For example, for the weight 1/4 pounds, there are three boxes that weighed 1/4pounds, so you have to write three tallies.

For "2/4 pounds", there were 2 boxes that had this weight, so you have to write two tallies.

For "3/4" pounds, there were 3 boxes that had this weight, so you have to write three tallies.

For "4/4 pounds", there was only one box that measures this weight, so you have to write one tally.

For the number line, you have to make a "dot plot", below the line you have to write each possible weight: 1/4, 2/4, 3/4, and 4/4. Then you have to draw points above each weight, one for each box that measured the said weight:

The heaviest box of raspberries weighed 4/4 pounds

The lightest box of raspberries weighed 1/4 pounds

To determine the difference between both of them you have to subtract 1/4 from 4/4:

`(4)/(4)-(1)/(4)=(4-1)/(4)=(3)/(4)`

The difference between the heaviest and the lightest boxes is 3/4 pounds.

To determine the total pounds that the class picked, you have to add the weights of all cartons:

`(3)/(4)+(1)/(4)+(2)/(4),(4)/(4)+(1)/(4)+(1)/(4)+(2)/(4)+(3)/(4)+(3)/(4)=5`

They picked 5 pounds of raspberries.
