How should you group the following expression to make it easier to add
18-9 4/9+7/9-8
To make it easier to add, group the expression as follows:
(18 - 9) + (4/9 + 7/9) - 8
To make it easier to add the given expression, you should group the terms with common denominators together. Here are the steps to group the expression:
Step 1: Begin with the given expression: 18 - 9 4/9 + 7/9 - 8.
Step 2: Combine the whole numbers 18 and -8: 18 - 8 = 10.
Step 3: Combine the two fractions with common denominators: 4/9 + 7/9 = 11/9.
Step 4: Now, the grouped expression becomes: 10 - 9 11/9.
Therefore, to simplify the expression by grouping terms, you have: 10 - 9 11/9.
