(5 + 7/11) * (6 + 17/110) is equal to 34.689 using a calculator which is approximately 35 to the units place by rounding up.

Let's ignore 17/110 it's a small number. 7/11 is more than half of unit between two whole numbers. Now let's rewrite original expression as (5 + 7/11)*6 we will get 30 plus (a little more than half of 6 which is) ~4, we will get ~34 close to 35 . So the answer is (b) 35 .
