What is similar about when you multiply decimals and divide decimals by a power of ten?
Both multiplication and division can be performed simply by moving the decimal point of the number: to the right if multiplying, to the left if dividing.
E.g. for 10, you can move the decimal point by one place to perform the operation.
Multiplication by 10: move decimal one place to the right (add zero if already a whole number).
Division by 10: move decimal point one place to the left (one place in if a whole number).

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?

How can you simplify a ratio?
Find a common number that you can divide both by, just like simplifying fractions. Say you have a ratio of 2:4. Both of those numbers are divisible by two, so if you divide both by two you get 1:2. Generally you want to have both numbers as whole numbers (i.e. no fractions or decimals) Find the GCF of the numbers and divide them both by it. If the GCF is 1, the ratio is in its simplest form. If the ratio is between two decimals, multiply them by whatever power of ten will eliminate the decimals. Then proceed with the GCF.

How do I multiply a fraction to a 100th power?
You can either calculate the fraction and raise the result to the 100th power or raise the numerator to the 100th power and divide it by the denominator raised to the 100th power.

When multiplying or dividing by a power of 10 what is the shortcut?
Move the decimal point, the same number of places as the power of 10. That way ---> to multiply. This way <--- to divide.
Why can you just move the decimal point to find a solution when you multiply or divide by but not when you multiply or divide by a number that is not a power of 10?
This is because we use the decimal system which is based on the fact that the place value of any digit is ten times that of the digit to its right.
