round down till there is not a decimal.
example: 4.4*5.6 round to 4*5= about 20 (lower estimate)
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.
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
round 1.998 to the four decimals as needed = 1.9980
how many decimals in hundredths round to 0.5
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.
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
4.0
The decimals of: 34.5, 34.6, 34.7, 34.8 and 34.9 all round up to 35
