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

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

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
