Answer 2

To calculate the expression (16 1/2 - 9 7/9) × y + 0.5, you first need to perform the subtraction inside the parentheses and then multiply the result by y, and finally add 0.5.

Let's break it down step by step:

1. Subtract 9 7/9 from 16 1/2:

   16 1/2 - 9 7/9

To subtract these mixed numbers, you can first convert them into improper fractions:

16 1/2 = 33/2 9 7/9 = 88/9

Now, subtract:

(33/2) - (88/9)

To subtract fractions, you need a common denominator, which in this case is 18 (the least common multiple of 2 and 9):

(33/2) * (9/9) - (88/9) * (2/2) (297/18) - (176/18)

Now, subtract the fractions:

(297 - 176)/18 121/18

2. Multiply the result by y:

   (121/18) * y

3. Finally, add 0.5 to the result:

   (121/18) * y + 0.5

So, the final expression is:

(121/18) * y + 0.5

You can simplify this expression further if needed, but this is the result of the calculation.
