Answer 3

[AI-generated answer — Bot GPT 3.5]

To evaluate the expression, we must first simplify it.

One way to simplify it is to convert the mixed numbers to improper fractions.

4 and 1/2 = (4 * 2 + 1) / 2 = 9/2
5 and 2/3 = (5 * 3 + 2) / 3 = 17/3

Now the expression becomes 9/2 - 2 - 17/3.

Next, we need to find a common denominator for the fractions 9/2 and 17/3.
The least common multiple of 2 and 3 is 6. So let's convert both fractions to have a denominator of 6.

9/2 = (9 * 3) / (2 * 3) = 27/6
17/3 = (17 * 2) / (3 * 2) = 34/6

Now the expression becomes 27/6 - 2 - 34/6.

To subtract these fractions, they must have the same denominator. So we can simplify the expression further:

27/6 - 2 - 34/6 = (27 - 34) / 6 - 2 = -7/6 - 2.

Now, let's find a common denominator for -7/6 and 2, which is 6:

-7/6 - 2 = (-7 - 12) / 6 = -19/6.

So, the value of the expression 4 and 1/2 - 2 - 5 and 2/3 is -19/6.

Answer 4

ok here are the options

-3 and 1 over 6

12 and 1 over 6

2 and 1 over 6

-4 and 1 over 6

Answer 5

Apologies for the confusion. Let's re-evaluate the expression:

4 and 1/2 - 2 - 5 and 2/3

Converting the mixed numbers to improper fractions:

4 and 1/2 = (4 * 2 + 1) / 2 = 9/2
5 and 2/3 = (5 * 3 + 2) / 3 = 17/3

Now the expression becomes 9/2 - 2 - 17/3.

Finding a common denominator for the fractions 9/2 and 17/3 (which is 6):

9/2 = (9 * 3) / (2 * 3) = 27/6
17/3 = (17 * 2) / (3 * 2) = 34/6

Now the expression becomes 27/6 - 2 - 34/6.

To subtract these fractions, they must have the same denominator. So we can simplify the expression further:

27/6 - 2 - 34/6 = (27 - 34) / 6 - 2 = -7/6 - 2.

Now, let's perform the calculation:

-7/6 - 2 = (-7 - (2 * 6)) / 6 = -19/6.

So, the value of the expression 4 and 1/2 - 2 - 5 and 2/3 is -19/6.

Therefore, the closest option is -3 and 1/6 (option A).

Answer 8

Simplify.​​​​​​​

7 and 2 over 3 + 5 and 1 over 4

Answer 9

[AI-generated answer — Bot GPT 3.5]

To simplify the expression, we must first convert the mixed numbers to improper fractions:

7 and 2/3 = (7 * 3 + 2) / 3 = 23/3
5 and 1/4 = (5 * 4 + 1) / 4 = 21/4

Now the expression becomes 23/3 + 21/4.

To add these fractions, we must first find a common denominator. The least common multiple of 3 and 4 is 12.

Converting the fractions to have a denominator of 12:

23/3 = (23 * 4) / (3 * 4) = 92/12
21/4 = (21 * 3) / (4 * 3) = 63/12

Now the expression becomes 92/12 + 63/12.

Adding the fractions together:

92/12 + 63/12 = (92 + 63) / 12 = 155/12.

So, the simplified expression for 7 and 2/3 + 5 and 1/4 is 155/12.

Answer 10

here are the options

-2

2 and 5 over 12

1 and 11 over 12

12 and 11 over 12

Answer 11

[AI-generated answer — Bot GPT 3.5]

After simplifying the expression 7 and 2/3 + 5 and 1/4, we found that the value is 155/12.

To determine which option matches the result, we can convert the improper fraction 155/12 back to a mixed number.

Dividing 155 by 12, we get:

155 ÷ 12 = 12 with a remainder of 11.

Therefore, the mixed number is 12 and 11/12.

Thus, the correct option is 12 and 11 over 12 (C).
