Where do you find decimal numbers in real life?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Since we normally count in tens, almost all the numbers that we come across are decimal numbers.
What decimal numbers come before zero?
Well, isn't that a happy little question! Before zero, we have all the negative decimal numbers, like -0.1, -0.2, -0.3, and so on. Each of these numbers may be small, but they're all important in creating a balanced and beautiful number line. Just remember, in the world of numbers, every value has its place and purpose.
What is the larger decimal 1.19 or 1.9?
To compare decimal numbers, you can add trailing zeros to make the numbers have the same number of decimal places. In this case, 1.19 can be written as 1.190. When comparing 1.190 and 1.900, you can see that 1.900 is larger because the digit in the tenths place is greater in 1.900 than in 1.190. Therefore, 1.9 is the larger decimal number.
How can rounding come in handy?
Decimal numbers in calculations often display a spurious degree of accuracy. By removing these unnecessary digits, rounding can simplify mathematical operations without compromising the results.
What is the process of changing a fraction to a decimal or to a percentage?
The answer depends on the form of the fraction. If it is a decimal fraction, you need to nothing to convert it to a decimal! (?). If it is in the form of a rational fraction, you need to use long division to divide the numerator by the denominator. The division will either come to an end or will go into a repeating loop of digits. The quotient from the division is the decimal equivalent. To convert to a percentage, simply move the decimal point two places to the right - inserting os if required.
