How should you group the following expression to make it easiest to add? 18-9 4/9+7/9-8
To make the expression easiest to add, you should group the numerators with their respective denominators.
The expression can be grouped as follows:
(18 - 9) + (4/9 + 7/9) - 8
To make it easiest to add, we can group the expression as follows:
(18 - 9) + (4/9 + 7/9) - 8
First, subtract 9 from 18:
9 + (4/9 + 7/9) - 8
Next, add 4/9 and 7/9:
9 + (11/9) - 8
Finally, subtract 8 from the previous result:
9 + (11/9) - 8 = 9 + 11/9 - 8
