If 4 notebooks weigh 2.8 pounds how do 6 notebooks weigh

6 * 2.8/4

4.2 because if you do order of operations then that comes out to be 4.2 pounds.

To find out how much 6 notebooks weigh, we can use the concept of a proportion.

First, we need to establish a relationship between the number of notebooks and their weight. From the given information, we know that 4 notebooks weigh 2.8 pounds. We can set up a proportion using this information:

4 notebooks = 2.8 pounds

Now, we can solve for 1 notebook:

1 notebook = 2.8 pounds / 4 notebooks

This can be simplified to:

1 notebook = 0.7 pounds

Now, we can apply this weight to find out how much 6 notebooks weigh:

6 notebooks = 0.7 pounds × 6 notebooks

By multiplying 0.7 pounds by 6 notebooks, we get:

6 notebooks = 4.2 pounds

Therefore, 6 notebooks weigh 4.2 pounds.
