Are natural numbers are decimal numbers?
Almost all numbers that we use in daily life are decimal numbers. The place value of each digit is ten times the place value of the digit to its right. And that is all that is required of decimal numbers. A decimal point is not necessary.
How can you order decimals fractions and mixed numbers on a number line?
The easiest way is to convert the mixed numbers and fractions to decimals by dividing the numerators (top) numbers by the denominator (bottom) numbers of each fraction - for a mixed number, the whole number needs to be added on.Then, comparing the whole numbers order as much as possible the numbers. Start with the tenths digit (the digit immediately to the right of the decimal point)Sort those groups of numbers with the same digits so far based on the current decimal digitIf there are still groups of numbers, use the next decimal digit (hundredth, thousandth, etc) until a distinction can be made.Where there are a group of numbers with the same whole number, start looking at the decimal digits:Write the list out of numbers out in their original form (decimal, fraction or mixed number).
How is adding fractions like adding whole numbers... How is it different?
Similarities: the sum does not depend on which number you start with (distributive)Differences: you must find a common denominator for the fractions (whole numbers have a common denominator [1]
What is an example for significant figures?
Significant figures are important for science, they tell how certain you are of a certain value. The rules for significant figures are as follows: If it is a decimal number, look at the first number on the left. If it is not zero, start counting the amount of numbers, and that's how many significant figures you have. For example, 7.495 has 4 significant figures. If it is zero, keep going until there is digit larger than zero, and start counting the numbers until the end. However many numbers there are, that's how many significant figures you have. For example, 0.000331 has 3 significant figures. If the number does not have a decimal, start from the right and if the number is not zero, start counting numbers and that's how many significant figures you have. For example, 93847 has 5 significant figures. If it is zero, the first significant figure will be the first non-zero digit. For example 3873000 has 4 significant figures. When you add or subtract some numbers, the amount of significant figures the answer should be expressed in depends on the number with the least amount of decimal places. For example, 4.398 + 5.2 = 9.6 You express the answer to the lowest number of decimal places a value you are adding or subtracting has. When you multiply or divide numbers, the answer is expressed to the lowest amount of significant figures that the values have. For example: 55 x 7 = 400 (when expressed with correct significant figures)
What is another name for counting numbers start with A?
The word you seek in this case is, ADDING.
