How should you group the following expression to make it easiest to add? 18-9 4/9+7/9-8
To make it easiest to add, you should group the expression as follows:
(18 - 9) + (4/9 + 7/9) - 8
To group the given expression to make it easiest to add, follow the order of operations (PEMDAS/BODMAS):
Step 1: Start by simplifying any fractions. In this case, we have 4/9 and 7/9 that can be combined.
- 4/9 + 7/9 = 11/9
Step 2: Next, perform the addition and subtraction from left to right.
- 18 - 9 + 11/9 - 8
Step 3: Work on the addition and subtraction of whole numbers:
- (18 - 9) + 11/9 - 8 = 9 + 11/9 - 8
Finally, the expression can be grouped as follows to make it easiest to add:
9 + 11/9 - 8
