To represent 0.3 pounds Ken should shade 3 columns
To represent the weight of all of the baseballs He should shade 7 times
The shaded part of this model will represent the expression 7 x 0.3 (7x 0.3 = 2.1)
The Total weight of the baseballs is 2.1 pounds
1) Gathering the data
7 baseballs each one weighs 0.3 pounds
7 x 0.3 = 2.1 ⇔2.1 : 0.3 = 7
Each tiny square corresponds to 0.01 of the block.
2.1 : 0.3 = 7
2) So the total weight (2.1) corresponds to 2 blocks and 0.1 blocks mean 1 column on the third block. Or, 2.1 = 7 x 0.3 Seven times three columns.
Examining the options:
3 ) We can answer each drop-down menu:
