you could multiply it by 5 to get a denominator of 100 to make it easier to convert, which would make it 15/100. Therefore you can easily deduce that the answer would be 0.15 & 15%

Answer: 0.15; 15%

Explanation:

Both decimals and percentages are easily represented in terms of 100. That is why the first step you should do is multiply the numerator and the denominator by 5 to easily do the conversions


(3*5)/(20*5) = 15/100

You are allowed to do this because in math, the two things you can do to manipulate terms are add 0 and multiply by one. Since we are multiplying both the numerator and denominator by 5, it is equivalent to multiplying by one.

Now, we must convert 15/100 into a decimal. Since 100/100 is 1, 15/100 can be expressed as 0.15.

Now, we must convert 15/100 into a percent. You can either multiply the decimal amount by 100 or you can just remove the 100 in the denominator and get 15%.
