Yes, just as long as it's at the end of the decimal. Hope that helped! :)
0.4 = 0.40 = 0.400 = 0.4000000000000 basically, you can add as many zeros as you want on to the end without changing the value.
You can add zeroes at the end of a decimal without changing its value because they represent additional precision without altering the quantity. For example, 2.50 and 2.5 are equivalent; the extra zero indicates that the number is measured to the hundredths place. This property is a result of the positional value of digits in the decimal system. Thus, adding zeroes simply reflects the same value in a different form.

23 hundredths = 23/100 = 0.23; you can add zeros after a decimal without changing the value, so 0.23 = 0.230 Now just subtract: 9.042 - 0.230: 9.042 -0.230 -------- 8.812
The fact that 0 is the additive identity.
The only other way to write 0.625 without changing its value is to add one or more trailing zeros. Example: 0.62500000 If you change the '6' or the '2' or the '5', or put anything between the decimal point and the '6', or hang anything on the end other than zero, then you change the value, and it's not the same as '0.625' any more.
explain why it is important to line up decimal numbers by their place value when you add or subtract them
To change decimal to percent:Go two places to the right then add the % sign.
You may add as many zeroes to the right of the last number (after the decimal point) as you like without changing the value. You do change the significance (for applications in chemistry and physics) but not the value. So 0.3, 0.30, 0.300, and 0.3000 would all be equivalent. An equivalent fractional representation would be 3/10.
If a number has no decimal you can add a point zero zero at the end of that number.
When changing a decimal into a percent, you can move the decimal point to the right two times, and then add the percent sign. Correct answer: 237%
It mean to add more decimal places to a value. Sometimes this will show a more accurate value, rather than a rounded up value which is being shown because there are not enough decimal places to show the value in full.
