The only decimals that are integers are ones such as 4.00000 or -5.00 or 100.0. If there is anything other than 0 after the decimal place it is NOT an integer. So to add them, just add the numbers to the left of the decimal place.
explain why it is important to line up decimal numbers by their place value when you add or subtract them
To convert a decimal into a percent, simply multiply the decimal by 100 and add a percent symbol, or in other words, move the decimal place two places to the right and add a percent symbol.
When doing your calculations, you should keep the values to as many digits as are available, then when you get to the final answer, look at the third decimal place (the thousandths place), and based on if it is 0-4 then you just truncate at the second decimal place, or if the thousandths place is 5-9 then add 0.01 to the number and then truncate at 2 decimal places.
Call 100 to be 100.000 then place it underneath the other number so the decimal points are in a vertical line, and then add, not forgetting the decimal point in the answer, in the same vertical line.
Move the decimal point two place to the left and add a percentage symbol.
to add decimals: -line up the decimal points -then starting at the farthest place to the right, add the decimal in each place -if the sum of the digits in a place are greater than nine,regroup the number to the place to its left. -check the sum by writing each decimal as an equivalent fraction and then adding these numbers or mixed numbers.
You just take the second decimal place, if its 5 or more then add one to the first decimal, if it's 4 or below then leave the second decimal as is. Then write out the number and leave in only the first decimal place that you may have or may not have changed. In this case it's 16.2
because u have moved the decimal one place therefore you will need to add a zero to fill in the space
move the decimal place two places to the right and add a percent symbol or you can simply multiply the decimal by 100
Place Value Charts help you because they put the decimal in the right place.
Move the decimal point one place to the right. If the decimal point is already at the end of the number, add a 0 to the extreme right before moving the decimal point.
The decimal in the number 3.14 is after the 3. Put the deciman point in the right place when you add those numbers.
Just look at the numbrs aftr the decimal. 1 decimal place means 0.8 Howevr, if the numbr's 2nd decimal is five and above (e.g. 0.85) you gotta add 1 to 8 and the answer is 0.9
1920%. You take the decimal and u move the decimal point of two place values to the right and add a percent sign *If there is nothing in the last space when u move over the decimal point add a zero in it's place. ex. 19.2 = 1920%
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
To multiply by 10, add a zero (move the decimal one place to the right.) To divide, take a zero away (move the decimal one place to the left.)
One. However, if the number already has a decimal point, you need to move the decimal point one place to the right, adding one zero if needed.
The thousandths place is the third decimal in a number. So you look at the fourth decimal. If it's between 0-4, you chop it off, end of story. If it's between 5-9, you chop it off anyway, but you add 1 to the third decimal. Examples : 3.12345. The fourth decimal is 4. Result : 3.123. 8.78596. The fourth decimal is 9. Result : 8.786 (notice it's not 8.785). If you have to add 1 to the third decimal and it's a 9, it becomes 0, and you have to add 1 to the second decimal. If it's a 9 too, it becomes 0, and you have to add 1 to the first decimal. And so on. Examples : 6.12981. The fourth decimal is 8. Result : 6.130. 5.49962. The fourth decimal is 6. Result : 5.500. 2.99988. The fourth decimal is 8. Result : 3.000. 9.99999. The fourth decimal is 9. Result : 10.000.
add a 0 to the back of the decimal
If you want to round to the first decimal place, look at the second decimal place.If that's 5 or more, add '1' to the first decimal place, and discard the rest.If it's less than 5, keep the first decimal place as it is, and discard the rest.2.543 rounded to the nearest tenth is 2.5 .
