How do you group the following expression to make it easiest to add 18 -9 4/9+7/9-8

Answer 1

To group the expression in order to make it easiest to add, you can first combine the whole numbers and fractions separately.

First, add the whole numbers:
18 - 9

Next, add the fractions:
4/9 + 7/9 - 8

Finally, combine the results of both additions.

So, the grouped expression becomes:
(18 - 9) + (4/9 + 7/9 - 8)
