When dividing a decimal by a decimal why do you need to had a zero to the right?
because u have moved the decimal one place therefore you will need to add a zero to fill in the space
What is 2.875 in fraction form?
Each time the decimal place is moved to the left, it is dividing the number by 10. So, 2.875 is the same as 2875/100, which simplifies to 115/4.
How do you write the standard number 5217000000 in scientific notation?
You move the decimal left or right until you end up with one digit in front of the decimal. Then, if you had to move the decimal to the left to get this number, you will have ten to the positive power of the number of decimal places moved. If you had to move the decimal to the right to get the number, you will have ten to the negative power of the number of decimal places moved. In this example, 5217000000 = 5.217 x 109

What moving the decimal point does to a number mathematically?
Multiplies it by an integral power of ten - positive if the decimal point is moved to the right and negative if moved to the left.
Convert to fraction notation?
Write a fraction with the decimal number as the numerator and 1 as the denominator. Move the decimal point in the numerator to the right whatever number of places required to make it a whole number. Add the same number of zeros to the right of the 1 in the denominator as the decimal point was moved. Reduce if possible by dividing both members by the same whole number. Example: 0.125 = .125/1 = 125/1000 = 1/8
How do you transfer numbers into scientific notation?
You put the first number in front of the decimal. Then you count how many times you had to move the decimal over and use that as the exponent for 10. If you moved your decimal to the right, the number is positive. If you moved the number to the left, the number is negative. Example: 7123 = 7.123 x 103 I
Why do you have to move the decimal over?
When you multiply or divide a number by 10, the decimal place is moved to the right or the left. Ie. 2.0 x 10 = 20.0 ( The decimal point was moved to the right for multiplication). Ie. 20.0 / 10 = 2.0 ( The decimal point was moved to the left for division).
What is the scientific notation for 0.196?
Move the decimal until the number's absolute value is between 0-10.0.196 ---> 1.96Count how many spaces you moved the decimal.1 spacePut "x10" after the number.1.96 x 10Put 10 to the power of the number of space you moved. If you moved it to the right, the power is negative. If you moved it to the left, the power is positive.1.96 x 10-1 is the answer.
How can you express a number in scientific notation?
To convert a number to scientific notation: · If the number has no decimal point, then add one at the end. · Then move the decimal point to just after the first digit while counting the number of places you have moved it. · The mantissa of the new number, formed after moving the decimal point is a. · If the original number is negative, then so is a. · The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative. For example: 23045.06 becomes 2.304506*10^4 -23045.06 becomes -2.304506*10^4 0.00023004 becomes 2.3004*10^-4
What is the scientific notation of 561?
5.61 x 102 , you just move the decimal so that the original number is greater than or equal to one but less than 10 then multiply that by 10 to the power of the number of decimal places you had to move. If you moved the decimal to the left, the exponent is positive, if you moved the decimal to the right, the exponent is negative.
