Question

Estimate the product of 204 and 0.46. explain what method of estimation you used and why it works.

Answer 1

For sake of convenience, you can multiply them by 10,

then it will become, 2040 * 46 =93840

Now, you should divide that by 100, = 93840/100 = 93.84

Did you like that idea??

If not, you can approach for basic one...but then you have to be careful about decimal..ok
