To calculate this expression, we follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) from left to right:

Calculate 4/11 7/10:
= (4 7) / (11 * 10)
= 28 / 110
= 14 / 55

Calculate 7/10 7 4/11:
= 7/10 (7 + 4/11)
= 7/10 (77/11 + 4/11)
= 7/10 81/11
= (7 81) / (10 11)
= 567 / 110

Subtract the results:
= 14/55 - 567/110
= (14 2) / (55 2) - 567 / 110
= 28 / 110 - 567 / 110
= (28 - 567) / 110
= -539 / 110

Therefore, 17 4/11 7/10 - 7/10 7 4/11 = -539 / 110.
