We read the number 3.3385 as "3 and 3385 ten thousandths," which, as a mixed number, is
![3 (3385)/(10,000)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/jvrhji82zgxa0jrtdcmlbmv5nw9mzbobb4.png)
We can reduce 3385/10,000 using the common factor 5, giving us the equivalent fraction 677/2,000. We can't reduce it any further, so we can say that
![3.3385 = 3(677)/(2,000)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/bke2v784qafnmdmat0d03udltztnd9v2yi.png)
To compare 3 5/16 to this number, we need to convert the fractional part to a denominator of 2,000. Since 2,000 = 16 x 125, we can multiply the numerator and denominator by 125 to find that
![3 (5)/(16)=3(625)/(2,000)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/jj8nbq2gkl5px4q92j56ed0ock391ltqf5.png)
Since 677 > 625, we can say that 3.3385 is larger than 3 5/16.
