Ok, so in other words, the decimal 0.1, is also known as 1/10. Because it is 1 tenth of one hundred, for the decimal place value. So, then you would want to multiply the 1/5 by 2, the top and bottom, numerator and denominator, by 2 to get it equal, or like terms, with 1/10. You would get 2/10. So, you are now looking for a number in between 1 and 2 with a denominator, or bottom number, of 100. To find that number, you will want to multiply the fractions, 1/10 and 2/10 by 10 get the denominator to 100. So, 1 times 10 is 10, and 10 times 10 is 100. So, you will end up with 10/100 for the first fraction and 20/100 for the second fraction. Then, you can make a fraction that has a whole number that is in between 10 and 20. I would pick 12, and then transfer that over to a decimal. So, it would become 0.12, since it is 12 percent, or 12 parts, of 100.
