Low Estimate and High Estimate?

Question

Hey I'm having trouble with my summer math packet:

Find a low estimate and high estimate for the product or quotient.

Here's a sample question-

238 x 87

I dont know what a low estimate and high estimate is. Help?

Answer 1

i have that packet also but i am having trouble with finding the amount of liquid in the measuring cup. you can barely see the cup.

Answer 2

You multiply and after you get your answer you round it
Example: 567*12=
                20706~
        Low:20710
        High:20700

Hope this helped, and just for the record I also have that
packet but I am in 2010  : D

Answer 3

8.6*8.762

Answer 4

A low and high estimate is if you have, like you said 238 x 87 you would multiply 200 and 300 and get 60,000 which is the high estimate and then you would do 80 x 90 and get 720 which is the low estimate. I'm pretty sure this is right but I'm not so sure.
