To solve this problem, we need to find the common denominator of 12 and 40, which is 120. Then, we can rewrite the expression as:
(17/12) - (49/40) = (17 * 10/120) - (49 * 3/120) = 170/120 - 147/120 = 23/120
Now, we can compare this value to the choices given:
A. 1/4 = 30/120
B. 1/5 = 24/120
C. 1/6 = 20/120
D. 1/7 = 17.14/120 (rounded to two decimal places)
Out of these choices, the value that is closest to 23/120 is C. 1/6, which is only 3/120 away. Therefore, we can conclude that the answer is C. 1/6.
