How do you solve 2 decimal numbers using multiplacation?
Multiply the numbers, count the total number of decimal places in the problem and place that many in your product.
How do you estimate 8.75 In decimal?
The number is already in decimal form so why would you want to estimate it in decimal form???
What is the rule of multipliying decimal?
One way is to multiply the numbers ignoring the decimal point. If the first multiplicand has d1 digits after the decimal point, and the second has d2 digits after the decimal point, then their product has (d1 + d2) digits after the decimal point.An alternative for the second stage is to estimate the answer to determine where the decimal point should go.
What is the closest estimate for the product of 2x19x5 using 1150 200 125 50?
200, as the actual answer is 190.
How do you find the number of decimal places in a product of decimal numbers?
To find the number of decimal places in a product of decimal numbers, add up the total number of decimal places in each of the factors. For example, if you have 2.5 multiplied by 4.75, there are two decimal places in 2.5 and two decimal places in 4.75, so the product will have a total of four decimal places.
Describe two strategies that you can use to estimate decimal product?
YOU CAN estimate it by if your product has more than 5
How do you estimate the product of a decimal and a whole number?
The answer depends on what the decimal is: the processes for 9999.02 and 0.02 are very different.
Using front end rounding, the best estimate of the product of 7.3 × 4 is?
28

How can you use estimation to check that you have placed the decimal point correctly in your product?
An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.
How do you find a low estimate for the product of two decimals round both factors to what?
round down till there is not a decimal. example: 4.4*5.6 round to 4*5= about 20 (lower estimate)

What is the decimal estimate for 0.74?
0.75 is a good estimate.
What can you find how finding a whole number estimate before your multiply the decimal can help you make sure your decimal placement is correct?
Not really.If you are competent in using the basic operations of arithmetic (+ - * /) and follow the riles as these apply to decimal numbers then the decimal point will be correctly placed and finding a whole number estimate will only mean additional calculations which serve no purpose. On the other hand, if you are not that competent then how can you be sure that the whole number estimate that you find is accurate?
