Homework Help: Math

Posted by Gee on Sunday, March 4, 2007 at 10:07am.

I need help with this question:

Estimate the product by rounding to
the nearest one

6.38 times 18.716

I said on my assignment 120 and my
teacher marked it wrong. She said it's
114, and I donot see how it's 114.

Any input, would certainly be welcome.

Thank you!

By rounding to the nearest 1, you are multiplying 6 x 19. That product is 114.

Before multiplying first round the numbers. It would be 6x19 then the answer comes out to be 114.
