Answer:

2494.756kg

*see below regarding significant digits

Explanation:

Set up a grid to help you to know whether to divide or multiply. Stack equivalent values one on top of the other in your grid. Arrange them so that the units will cancel out. This helps you to change the units. See image.

*if you are also learning about "significant digits" then you will have to alter the answer to only include the same number of significant digits as in the question.

The exact calculated answer is 2494.756, but there are only two significant digits in the question, so the answer maybe 2500kg instead. If your teacher hasn't taught sig figs then go with the exact answer.

2494.756kg
