First lets take away the negative sign for now Now lets separate the number into its two components which are 11 and 0.16 Now lets rewrite it to 16/100 Next we want to find the greatest common factor between 16 and 100 which is 4 since 4 * 4 equals 16 and 4 * 25 equals 100 so its 4. Now lets divide 16 and 100 by the greatest common factor so its sixteen divided by 4 over 100 divided by 4 Next we simplify all together which is 4/25 You remember that number 11 we had earlier, well we are going to go grab him back and add him to the fraction and make it 11 4/25 but... remember that negative sign, I said for now, right, so lets put him back on the spotlight.
