The science teacher ordered a total of 8 magnets.
To find the number of magnets the science teacher ordered, you can use the formula:
Number of magnets= Total weight/ Weight per magnet
In this case, the total weight is 5.2 pounds, and each magnet weighs 0.65 pounds.
Plug in these values into the formula:
Number of magnets= 5.2/0.65
Now, calculate the result:
Number of magnets=8
So, the science teacher ordered a total of 8 magnets.
