When changing fractions to decimals, look for an equivalent fraction that change the denominator to a power of ten
Power of 10 means that your denominator will look something like 10, 1000, 10000, and so forth...
Let us illustrate this with examples.
Example #1
Change 3/50 to a decimal
Notice that 50 was multiplied by 2 to get 100
Just remember that whatever you do for your denominator, you have to do it for your numerator
Example #2
Change 2/5 to a decimal
Example #3
Change 4/125 to a decimal
Notice here that 125 was multiplied by 8 to get 1000 because 125 × 8 = 1000
Therefore,when doing those problems,one of the big challenges is to find the number that you need to multiply the denominator to get 10, 1000, 10000, and so forth
You can find it by doing division. For instance 1000/125 = 8
