What is \(1 \frac{6}{7} - 1 \frac{4}{11}\)?

Convert both numbers to improper fractions, and to do that, multiply the denominator and whole number, and add the numerator.
If done correctly, you should get 13/7 - 15/11.
Now, we have to find the LCM of both denominators. 77 is the LCM.
77 is the LCM.
You needed to multiply 7 by 11 to get 77, so multiply 13 by 11, too. 13 x 11 = 143 We get 143/77.
Do the same with the other fraction. You needed to multiply 11 by 7 to get 77. So multiply 15 by 7. 15 x 7 = 105 We get 105/77
Now you can subtract.
143/77 - 105/77 = 38/77
