Standard notation is easy to find because it is everywhere. Standard notation is what you read in writing for example.

13/25 decimal notation

It is simply: 132.0

find the common for of the number. for instance move the decimal over to the right if positive or to the left if negative 12,400 .0035

42.3 is already in its decimal notation but it can be written as 423/10 as an improper fraction.

how can you use expanded notation to find an equivalent decimal

Just remember that there is one digit to the left of the decimal in scientific notation. All the other digits go on the right of the decimal. Then find an appropriate power of ten to write the rest of the number. Your 3,400 in scientific notation is 3.4 x 104in scientific notation.

Exponential notations are ways of writing very large or very small numbers using exponents. The first step is to add or move the decimal point. For a number like 0.00435 you move the decimal to make it 4.35, or for 345,000 the decimal would be 3.45. After moving the decimal you count how many spaces. If the decimal moved to the right then it looks like 4.35*10^-3 and when moving left it would read 3.45*10^5.

To find what number is 10 percent of 527, convert 10% to decimal notation and multiply that by 527. 10% is .10 in decimal notation, so 10% of 527 is 0.10*527 = 52.7

you can find it by putting it in expanded from

Just remember that there is one digit to the left of the decimal in scientific notation. All the other digits go on the right of the decimal. Then find an appropriate power of ten to write the rest of the number. Your 2042 is 3.76 x 105 in scientific notation.

Just remember that there is one digit to the left of the decimal in scientific notation. All the other digits go on the right of the decimal. Then find an appropriate power of ten to write the rest of the number. Your 0.005219 is 5.2 x 10-3 in scientific notation.

Convert back to standard notation. Subtract, then convert back to sci. notation.

The easiest way to find a percent is to turn the percentage into a decimal. You do this by placing the percentage over 100. 42% is the same as 42/100, which equals .42 in decimal notation. Now, take the decimal notation and multiply it by your number, in this case 125. .42 * 125 = 52.5

To find what number is 92 percent of 115, convert 92% to decimal notation and multiply that by 115. 92% is .92 in decimal notation, so 92% of 115 is 0.92*115 = 105.8

Take the diameter, then divide by 2 to get the radius. To get to scientific notation, put the number in the form of one digit followed by a decimal point, then the rest of the number, followed by x10n, where n is the number of places that you had to move the decimal point to get just one digit to the left of the decimal point. For example: diameter of 8. Divide by 2 to get 4. To get to scientific notation, make it 4X100. You didn't have to move the decimal point at all, so n=0. Example #2: Diameter of 250. Divide by 2 to get radius, which is 125. To make it scientific notation, you have to move the decimal point 2 places to get 1.25X102. If you had to move the decimal point to the right, then make n a negative number. Example #3: Diameter of 1/10. Divide by 2 to get radius of 1/20, or 0.05, which in scientific notation is 5X10-2.

Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1

The number of decimal places in the product is the SUM of the decimal places in the multiplicands.

The number after the decimal.

Divide the numerator (the top number) by the denominator (the bottom number) and you will get a decimal number.

You find scientific notation in Excel under the Format - Number menu.

Underlining is used in questions asked about decimals, not in decimal notation.A bar across the top of a decimal number means that the number (or numbers) are repeated infinitely as the decimal equivalent of a fraction, such as 1/3 (0.3333) or 1/7 (0.142857142857142857).

It is a requirement to find a decimal representation which has only a finite number of digits after the decimal point.

Extract from the mass number (in the hyphen notation) the atomic number.
