To group the expressions in a way that makes it easier to add the numbers, you should group the integers together and the fractions together.
First, add the integers:
18 - 9 = 9
Then, add the fractions separately:
4/9 + 7/9 = 11/9
Finally, subtract the last integer:
9 - 8 = 1
So the final result is 1 + 11/9 = 20/9 or 2 2/9.
How should you group the following expressions to make it easier to add 18 -9 4/9+7/9-8
