How do you multiply and divide decimals by powers of ten?
move the decimal point how much zeros that is in the number multiply to the Right, divide to the Left 18.75 X 100= 1875 !8.75/100= 0.1875
How do you change 6.25 from percent to decimals?
If you mean 6.25 percent, then you just divide by 100 (move the decimal point 2 places to the left). If you mean 6.25, then multiply by 100 (move the decimal point 2 places to the right)
What are two methods for determining the placement of the decimal point in the product?
When you multiply decimals, the decimal point is placed in the product.
What is similar when you multiply decimals and divided decimals by powers of ten?
You move the decimal place by as many positions as the number in the exponent.Examples (using "^" for powers): * To multiply by 10^5, you move the decimal point 5 positions to the right. * To multiply by 10^(-6), you move the decimal point 6 positions to the left. * To divide by 10^6 is the same as to multiply by the reciprocal - by 10^(-6). See the previous example.
Why can you just move the decimal point to find a solution when you multiply or divide by 101001000but not when you multiply or divide by a number that is not a power of 10?
You cannot just move the decimal when you multiply or divide by 101001000.
How do you divide withe decimals?
Its less awkward with decimals with a decimal point to multiply the top and bottom out to remove the decimal points. example: divide 125.24 by 8.6 so 125.24/8.6 , so multiply top and bottom by 100, gives 12524/860 , then divide out, the result is the same.

How do you work out how to change a decimal to a fraction?
For example, in a fraction like 2.534, there are 3 decimals after the point; in this case, take the point away, and divide by 1000 (a one with 3 zeroes). The result is 2534 / 1000.For example, in a fraction like 2.534, there are 3 decimals after the point; in this case, take the point away, and divide by 1000 (a one with 3 zeroes).

When you multiply decimals do you move to right or left?
When you multiply decimals, you do not move the decimal point during the multiplication process itself. Instead, you multiply the numbers as if they were whole numbers, and then you count the total number of decimal places in both the factors. The decimal point in the product is placed so that it has the same number of decimal places as the total counted.
Multiply decimals by 0.01?
Move the point two places left; eg 3465.76 x 0.01 = 34.6576
How do you express decimals to percent?
Multiply by 100 (move the decimal point twice to the right). For example, 0.50 = 50%
How do you divide 1.73 and didvide it by 519 using decimals?
To divide 1.73 by 519 using decimals, you first set up the division problem as follows: 1.73 ÷ 519. To divide, you move the decimal point in the dividend (1.73) to make it a whole number, which becomes 173. Then, perform the division as you would with whole numbers. The quotient is 0.00333 (rounded to five decimal places).
How do you convert between fractinons and decimals?
Fractions to decimals: Divide the numerator by the denominator. Decimals to fractions: Put the fraction without the decimal point in the numerator. In the denominator, put a "1", followed by as many zeroes as there are decimals. For example, 0.058 becomes 58 / 1000.
