Estimating help determine the order of magnitude of the answer. It is, therefore, a simple matter to place the decimal point is such a way that the order of magnitude of the calculated answer matches that of the estimate.
Before comparing the two numbers, you must first find the product of 1.2 and 3.6. To multiply with decimals, first multiply the numbers as if they didn't have any.12 x 36 = 432Now, to place the decimal point correctly in the answer, count the number of places that are in the original multipliers (1.2 and 3.6). There are two: .2 and .6. So, place the decimal in the product two spaces from the right. Your answer now becomes 4.32, which is less than 5.
decimal place
The product is 0.0036 Simple method is to multiply the two numbers. The decimal place is determined by the addition of the number of decimal places in each factor (2 places in 0.04, 2 places in 0.09), 2 +2 = 4.
Anything to one decimal place has a precision of one decimal place. For instance, 1234 to one decimal place is 1000, and 5678 to one decimal place is 6000. If you are talking fractional examples, then 0.1234 to one decimal place is 0.1 and 0.5678 to one decimal place is 0.6. Similarly, 0.001234 is 0.001, and 0.005678 is 0.006.
I need what is the decimal place is mean
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.
It could be 0.2 to one decimal place.
0.8 to one decimal place or 1 as a whole number.
4 as a whole number or 4.2 to one decimal place.
By estimating the product it gives an indication of how big the final answer should be; knowing this, the decimal point can be put in to give an answer of the correct size. For example if the product estimate is 125 and the actual answer (without the decimal point) is 136728, then the decimal point needs to be inserted to make the answer about 125; the place is therefore after the 136, making the answer 136.728 (= 5.4 x 25.32 ≈ 5 x 25 = 125)
* One decimal place. * To the tenth place.
The number of decimal places in the product must equal the total number of decimal places in the factors. John's product should have 2 decimal places.
If the two decimal numbers have x and y digits after the decimal points, then the product has (x + y) digits after the decimal point.
two.
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
4*5 = 20 so the answer should be around 20.
Two places.
