How do you change 1.66 into a fraction?
Simplified, it is 1
When written in decimal form, 0.1 is a tenth, or 1 out of 10.
0.01 is a hundredth, or 1 out of 100. So 0.66 is 66 hundredth, or 66 out of 100. When there is a number in front, you just write the fraction as a mixed. Don't forget, most teachers want everything in simplified form. Hope I helped!!
