to find a low estimate for the product of two decimals, round both factors
When you round both factors in a multiplication problem up, your estimate will be greater than the actual product.
4 decimals: 1.0033 3 decimals: 1.003 2 decimals: 1.00
You know when to overestimate when the last number is over five then you round it up. Under is the last number below five you round down.
To mentally estimate the product of 313 and 489, you can round both numbers to the nearest hundred to simplify the calculation. 313 rounds to 300 and 489 rounds to 500. Multiply these rounded numbers together to get 300 x 500 = 150,000. This is a rough estimate of the product of 313 and 489.

round down till there is not a decimal. example: 4.4*5.6 round to 4*5= about 20 (lower estimate)
When you round both factors in a multiplication problem up, your estimate will be greater than the actual product.
overestimate
I think you round it to the nearest whole number...
To round to estimate the product of 38 x 2, you first round each number to a more manageable value. In this case, you can round 38 to 40 and 2 to 0. Then, multiply the rounded numbers together to get an estimate of the product. In this case, 40 x 0 = 0. So, the estimated product of 38 x 2 is 0.
Yes
Because some decimals are really long and hard to write down. Especially if they're not repeating ones. So people round them to be able to say them or write them.
round 1.998 to the four decimals as needed = 1.9980
how many decimals in hundredths round to 0.5
The answer is 2,800. To estimate the product of 2 numbers, you round to the nearest ten or hundred. In this case, you would round 73 to 70, and 403 to 400, to make it easy to multiply. 70 x 400 = 2,800

The decimals of: 34.5, 34.6, 34.7, 34.8 and 34.9 all round up to 35
