How would you solve this as an estimation?

**-**2/3."

There is probably a typo where the minus sign was missed out in the last choice.

If that is the case, then you should be able to find the right one when you see that the answer is negative:

1/9 + 2/5 - 1/3 - 3/4

=(1/9 - 1/3) + (2/5 - 3/4)

by rearranging the terms (associative property of addition)

Both groups of terms in parentheses are negative, so which choice would you take?
