What is 8 − 7 1/4?
To subtract 7 1/4 from 8, first convert 8 to a fraction with the same denominator as 7 1/4.
8 is equivalent to 8/1.
To find a common denominator, we multiply 4 by 1 to get 4, then multiply 7 by 4 to get 28.
Now we have 8/1 - 28/4.
To subtract the fractions, we need to find a common denominator. In this case, it is 4.
8/1 can be rewritten as 32/4, since multiplying the numerator and denominator by 4 gives the same value.
Now we have 32/4 - 28/4.
Subtracting the fractions, we get 4/4.
Therefore, 8 - 7 1/4 equals 4/4 or simply 1.

Apologies for the confusion. Let's calculate it again:
To subtract 7 1/4 from 8, we can convert both numbers to fractions with the same denominator.
8 can be converted to 32/4, since 8 equals 32/4.
Now, we have 32/4 - 7 1/4.
To subtract the fractions with the same denominator, we subtract the numerators and keep the denominator the same.
32/4 - 7 1/4 = (32 - 7) / 4 = 25/4.
Therefore, 8 - 7 1/4 equals 25/4 or 6 1/4.
no the answer is 3/4
Apologies for the mistake. Let's calculate it correctly this time:
To subtract 7 1/4 from 8, we can convert both numbers to improper fractions.
7 1/4 can be converted to 29/4, since 7 * 4 = 28 and adding 1 gives us 29.
Now, we have 8 - 29/4.
To subtract fractions, we need a common denominator. In this case, it is 4.
8 can be written as 32/4 because 8 * 4 = 32.
Now we have 32/4 - 29/4.
Subtracting the numerators, we get 32 - 29 = 3.
The denominator remains the same, which is 4.
Therefore, 8 - 7 1/4 equals 3/4.
What is −4 5/11 − 2 4/11
To subtract -4 5/11 from -2 4/11, we need to find a common denominator.
The denominators are already the same (11) in this case.
Now, we can subtract the whole numbers and the fractions separately.
For the whole numbers, -2 - (-4) = -2 + 4 = 2.
For the fractions, 4/11 - 5/11 = -1/11.
Combining these results, we have 2 - 1/11.
Therefore, -4 5/11 - 2 4/11 equals 2 - 1/11, or 1 and 10/11.
you sure?
Apologies for the mistake. Let's calculate it correctly this time:
To subtract -4 5/11 from -2 4/11, we can first convert both numbers to improper fractions.
-4 5/11 can be written as -49/11, since -4 * 11 = -44 and adding 5 gives us -49.
-2 4/11 can be written as -26/11, since -2 * 11 = -22 and adding 4 gives us -26.
Now, we have -49/11 - (-26/11).
To subtract fractions, we need a common denominator. In this case, it is 11.
Therefore, -49/11 - (-26/11) = -49/11 + 26/11.
By adding the numerators, we get -49 + 26 = -23.
The denominator remains the same, which is 11.
Therefore, -4 5/11 - 2 4/11 equals -23/11.
Converting it to a mixed number, we have -2 1/11.
