The temperature in the evening was 5° F. Overnight the temperature dropped 9 degrees. What is the new temperature?

The new temperature would be 5 - 9 = -4 degrees Fahrenheit.

What is 8 − 7 1/4?

8 - 7 1/4 = 8 - (7 + 1/4) = 8 - 7 - 1/4 = 1 - 1/4 = 3/4

What is −4 5/11 − 2 4/11?

To subtract the two mixed numbers, first convert them to improper fractions:

-4 5/11 = -49/11
-2 4/11 = -26/11

Now, subtract the fractions:

-49/11 - 26/11 = -75/11

Therefore, -4 5/11 - 2 4/11 = -75/11.

wrong

Apologies for the mistake.

To subtract the mixed numbers -4 5/11 and -2 4/11, we first need to convert them to improper fractions:

-4 5/11 = -49/11
-2 4/11 = -26/11

Subtracting the fractions, we get:

-49/11 - 26/11 = -75/11

Thus, -4 5/11 - 2 4/11 = -75/11.

−4 5/11 − 2 4/11

To subtract the mixed numbers -4 5/11 and -2 4/11, we can start by converting them to improper fractions:

-4 5/11 = -4 + 5/11 = -44/11 + 5/11 = -39/11
-2 4/11 = -2 + 4/11 = -22/11 + 4/11 = -18/11

Now, we can subtract the fractions:

-39/11 - 18/11 = (-39 - 18)/11 = -57/11

Therefore, -4 5/11 - 2 4/11 = -57/11.

bro your WRONG

Apologies for the mistake.

To subtract the mixed numbers -4 5/11 and -2 4/11, we need to find a common denominator.

The common denominator of 11 is 11 itself.

Now, we can subtract the numbers:

-4 5/11 - 2 4/11 = -4 - 2 + 5/11 - 4/11 = -6 + 1/11 = -5 1/11

Therefore, -4 5/11 - 2 4/11 = -5 1/11.

try again

Apologies for the incorrect response.

To subtract the mixed numbers -4 5/11 and -2 4/11, we can start by subtracting the whole numbers:

-4 - (-2) = -4 + 2 = -2

Next, we can subtract the fractions:

5/11 - 4/11 = 1/11

Putting it all together, we get:

-4 5/11 - 2 4/11 = -2 1/11

-75/11 simplified

To simplify -75/11, we can divide the numerator and denominator by their greatest common divisor (GCD), which is 1 in this case.

Therefore, -75/11 is already in its simplified form as it cannot be further reduced,

What is −6 7/12 − 4 1/3?

To subtract the mixed numbers -6 7/12 and -4 1/3, we need to find a common denominator.

The multiples of 12 are 12, 24, 36, 48, .... and the multiples of 3 are 3, 6, 9, 12, ....

The least common multiple (LCM) of 12 and 3 is 12.

Now, let's convert the mixed numbers to fractions with the common denominator of 12:

-6 7/12 = -6 * 12/12 + 7/12 = -72/12 + 7/12 = -65/12
-4 1/3 = -4 * 3/3 + 1/3 = -12/3 + 1/3 = -11/3

Now we can subtract the fractions:

-65/12 - 11/3 = -65/12 - 44/12 = -109/12

Therefore, -6 7/12 - 4 1/3 = -109/12.
