It is then 3.4 rounded up to one decimal place
The correct answer is 23.1
to convert scientific notation to decimal you count the number of spaces up to the last digit then put the decimal point then put x10 to the power of if how many places you move the decimal point.................................
Because left of the decimal point goes times 10 for every position and right of the decimal point goes times -10 for every position.
To subtract 0.5 from 0.05 first line up the decimal points in your equation. If you need to add a zero behind the 5 in 0.5 so you get 0.50. Then subtract as if there was no decimal point (take it as 50-5). After you subtract bring the decimal point down. You should end up with 0.45.
Bring the decimal straight up then divide
4.98 Simple rule: 'point 5 and above goes up'. For two decimal places, if the third digit is 5 or greater, the second digit goes up by one.
Divide the mark-up amount as a decimal fraction of the pre-mark-up.
Put the decimal point for the quotient exactly above the decimal point in the dividend. Then forget about it, and just keep your digits lined up as you do the division. The decimal point winds up exactly where it belongs in the quotient.
There is no such thing as the nearest decimal point - since there is only one decimal point. To the nearest whole number, the value is 3.
Unlike addition, there is no need to line up the decimal points. Just multiply ignoring the decimal points. When you are done, move the decimal point of the result to the left equal to the number of digits after the decimal point for both multiplicands.
Line up the decimal points in a vertical column. Then add the numbers while ignoring the decimal point. Finally, put a decimal point in the answer in the same column as for the summands.
In the whole number 565, the decimal point is "hiding" after its last digit, ie 565.In the place value system, the decimal point always follows the units digits; however, if there are no digits after the decimal point, ie the number is a whole number, it is not normally written and ends up "hiding" after the last digit of the number.It is not normal to start or end a number with a decimal point as it can so easily get lost, so to show the decimal point in a whole number, it is usual to write "point zero" after the number, ie 565.0It depends on what the question is.It can possibly be 5.65 , 56.5 , or .565 .Hope this can maybe help you!-Sherratyn-
Immediately to the right of the decimal point.

78.46 write above each other with decimal point in same place ... 70.00 08.00 00.40 00.06 then add up
It is then 3.4 rounded up to one decimal place
