The number 2.15 has a whole number (2) and a fractional part (0.15).<\/p>\n<p>Rounding a decimal means to change it to a whole number. The number 5.4, for example, can be rounded to 5.

The number ten is written as a 1 followed by a 0. The number one hundred is written as a 1 followed by two zeroes. The number one thousand is written as a 1 followed by three zeroes. Decimals can be written in three different ways. The most common way to write a decimal is to use a period to mark the end of the number. Another way to write a decimal is to use a comma to mark the thousandths place. The third way to write a decimal is to use a point to mark the tenths place.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_is_Estimation_Important\"><\/span>Why is Estimation Important?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the most important aspects of project management is estimation. Estimation is the process of predicting the amount of time, effort, and resources necessary to complete a project or task. It is an important tool for project managers because it allows them to plan and budget for their projects, as well as track the progress of their teams. Good estimation also allows project managers to identify potential risks and issues early on in the project, so that they can take steps to prevent them from becoming problems.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Round_Off_Decimal_Numbers\"><\/span>How to Round Off Decimal Numbers?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To round off a decimal number, first identify the place value of the last number to be rounded. If the number to the right of the last number is 5 or more, round the number up. If the number to the right of the last number is less than 5, round the number down.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Rounding_Off_Whole_Numbers\"><\/span>How to Rounding Off Whole Numbers?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To round off a whole number, look at the number after the decimal point and decide how many places to round it off to. If the number after the decimal point is 5 or more, round it up. If the number after the decimal point is 4 or less, round it down.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Rounding_Decimal_Numbers_Using_Number_Line\"><\/span>Rounding Decimal Numbers Using Number Line<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To round a decimal number using the number line, simply look at the number to the right of the decimal point and see how many places you need to move the decimal point to the right to get a whole number. If there are not enough places to move the decimal point to the right, then just round up.<\/p>\n<p>For example, if you want to round the number 5.512 to the nearest whole number, you would move the decimal point two places to the right to get 7.512. If you want to round the number 5.512 to the nearest tenth, you would move the decimal point one place to the right to get 5.51. If you want to round the number 5.512 to the nearest hundredth, you would move the decimal point two places to the right to get 5.51200.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What are Rounding Decimals?
