It is NOT a place holder though, for really big (or small) numbers it can help find the place value.
It is called a separator or delimiter.
A filtration apparatus is for example a separation device.
The Continental Divide of the Americas is an example of a mountain ridge that separates river systems. Further examples include Northern Divide or Laurentian Divide.
Sometimes the pronoun "it" refers to a thing or idea. For example: If you see my pen, put it on my desk. Sometimes the pronoun "it" is an impersonal placeholder. For example: It is going to rain tomorrow.
It seems like "senarator" is a typo or misspelling. If you meant "separator," it typically refers to a tool or device used to separate or divide items or elements. For example, in computing, a separator is often used to distinguish different parts of a file or data.
It is required as a placeholder, to put other digits in its correct place. For example, in 102, the 1 is in the hundreds place. Without the zero, it would be in the tens place.
A zero placeholder is necessary when adding or subtracting decimals to ensure that numbers are aligned correctly according to their place values. For example, if you have 2.5 and 1.75, it helps to write 2.50 to clearly align the tenths and hundredths places. This alignment prevents errors in calculations by maintaining the proper value of each digit, allowing for accurate addition or subtraction. Without the placeholder, it could be easy to miscalculate by misaligning the digits.
'WikiAnswers Local' Is a Placeholder CategoryPLEASE NOTE: No new questions should be added to the main "WikiAnswers Local" category."WikiAnswers Local" is a placeholder category for questions about certain countries where English is spoken (Australia; Canada; India; New Zealand; Philippines; South Africa; and the United Kingdom).
The period that separates two parts of a decimal is called the decimal point. It distinguishes the whole number part from the fractional part of a number. For example, in the decimal 3.14, the decimal point separates the whole number 3 from the fractional part 14.
For example, it could be shown that water is made of other substances by electrolysis, that separates it into oxygen and hydrogen.
None - unless you use the word 'and' as a separator - For example 'one hundred and fifty' as opposed to 'one hundred fifty'
Nothing separates a mountain range from land, the mountain range itself is what separates. For example, the Pyrenees separate France, Spain, and Andorra from each other as it is the border. However, nothing separates the Pyrenees from the rest of Europe.
An example of a mixture that separates into layers is oil and water. These two substances do not mix well and will form distinct layers due to their different densities. This separation is due to the immiscibility of the two substances.
