Question

How should you group the following expressions to make it easier to add 18 -9 4/9+7/9-8

Answer 1

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.
