How would you group the following expression to make it easier to add?
18−9 4/9+7/9−8
To group the expression to make it easier to add, we can first combine the whole numbers and the mixed numbers separately before adding them.
Expression: 18 - 9 4/9 + 7/9 - 8
1. Combine the whole numbers:
18 - 8 = 10
2. Combine the mixed numbers:
9 4/9 + 7/9 = 9 + 7/9 = 16/9
Now we have the grouped expression:
10 + 16/9 - 8
By grouping the expression in this way, it becomes easier to add because we have simplified it to only whole numbers and fractions.
nope
I apologize for the misunderstanding. To group the expression to make it easier to add, we can rearrange the terms and group them according to their types:
Expression: 18 - 9 4/9 + 7/9 - 8
Rearranged expression with grouped terms:
(18 - 8) + (-9 4/9 + 7/9)
Now we have the grouped expression:
10 + (-9 4/9 + 7/9)
By grouping the terms in this way, it becomes easier to add because we have separated the whole number from the mixed number.
once again nope
I apologize for the confusion. To group the expression in a way that makes it easier to add, we can use parentheses to clearly define the different terms:
Expression: 18 - 9 4/9 + 7/9 - 8
Grouped expression using parentheses:
(18) - (9 4/9) + (7/9) - (8)
By using parentheses, we have clearly separated each term in the expression. This makes it easier to add the terms together by focusing on one group at a time.
for the third time no
I apologize for my previous incorrect responses. To group the expression in a way that makes it easier to add, we can regroup the terms based on their similarity:
Expression: 18 - 9 4/9 + 7/9 - 8
Grouped expression based on similarity:
(18 - 8) + (-9 4/9 + 7/9)
Simplified expression:
10 + (-8 + -9 4/9 + 7/9)
By regrouping the terms based on their similarity, we can now add the terms more easily.
STILL WROONGGG
I apologize for the confusion. Let's try grouping the terms in a different way:
Expression: 18 - 9 4/9 + 7/9 - 8
To group the expression in a way that makes it easier to add, we can first combine the whole numbers and the fractions separately:
18 - 8 + (-9 4/9 + 7/9)
Next, we want to add the fractions:
-9 4/9 + 7/9
To do this, we need to find a common denominator, which in this case is 9:
-9 4/9 + 7/9 = -9 + 7 + 4/9 = -2 + 4/9
Now, let's substitute this result back into the original expression:
18 - 8 + (-2 + 4/9)
Finally, we can add the remaining terms:
18 - 8 - 2 + 4/9 = 8 + 4/9
Therefore, the grouped expression that is easier to add is:
8 + 4/9
To group the following expression in a way that makes it easier to add, we can combine the like terms.
The given expression is: 18 - 9 4/9 + 7/9 - 8.
To add fractions, we first need to find a common denominator. In this case, the common denominator is 9.
Now, let's group the terms together:
(18 - 9) + (4/9 + 7/9) - 8
To simplify, we can perform the calculations within each group:
(9) + (11/9) - 8
Next, let's add the fractions:
9 + (11/9) - 8
To add a mixed number (9) with a fraction (11/9), we convert the mixed number to a fraction. In this case, we convert 9 to the fraction 9/1:
(9/1) + (11/9) - 8
To add fractions, we need a common denominator, which is 9:
(9/1) + (11/9) - (8 * 9/9)
Now we can combine the fractions:
[(9 * 9) + 11] / 9 - (72/9)
Calculate the numerator:
(81 + 11) / 9 - (72/9)
Simplify:
92/9 - 72/9
Finally, subtract the fractions:
(92 - 72) / 9
Solve the numerator:
20/9
Therefore, the expression "18 - 9 4/9 + 7/9 - 8" simplifies to "20/9."
