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.
75.461
the answer is 5.7 million
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...
Round 38 to 40. Estimate the product as 80. The actual product is 76.
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.
how many decimals in hundredths round to 0.5
round 1.998 to the four decimals as needed = 1.9980
4.0
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
Your estimate will be greater than the exact number.
