How can estimating products you place the decimal correctly

The placement of the decimal point creates a significant change on the value of the number. The values of 6500.00 and 650.00 are different by 10 times although they only differ in the placing of the decimal point. This is important when estimating the sum of all decimal numbers. You'll just have to round off the numbers to the nearest ones place to determine the estimated closest sum in whole numbers.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
