first you need to shift the decimal point can you shift the decimal point?
well I'm going to give you a hint so you can remember it when you need to do a problem that inbolts changing decimals into a percent .you need to remember this word they are dominos,Pizza,and rock. here are the definitions for the example.
dominos:decimals
pizza:percent
rock:right
the rock tells you were to move the decimal point and rock means right so to shift the decimal point you always you need to move it to the right 2 times and that's how to make a decimal into a percent

You eliminate the decimal point, and put that in the numerator. Then you count the number of digits in the original decimal, and put a one, followed by that amount of zeroes, into the denominator.
For example:
8.25 = 825/100. (The denominator is a 1, followed by 2 zeroes, since the original decimal hat two digits after the decimal point.)
Finally you may want to simplify the fraction. The only possible prime factors for powers of 10 are 2 and 5.
Only if the decimal is a rational number can it be expressed as a fraction as for example 0.625 = 625/1000 which is 5/8 in its lowest terms
If you know how to turn a mixed number into a fraction and a fraction into a decimal do that then make it negative.
Make the mixed number into an improper fraction and then divide the numerator into the denominator and then move the decimal to the left two places!!!!!!!(:
8 12/100 Make a decimal
0.07 = 7/100
you can change a fraction to a decimal by dividing the bottom number into the top number.
