To solve this, you need to find a common denominator for the fractions. The common denominator for 30, 20, and 10 is 60. So, eleven thirtieths can be written as 22 sixtieths, nine twentieths as 27 sixtieths, and three tenths as 18 sixtieths. Adding them together yields 67 sixtieths, which can be simplified to 1 and 7/60.
