What is −4 5/11 − 2 4/11?(1 point)
To subtract mixed numbers, you need to find a common denominator for the fractions involved. In this case, the common denominator is 11.
Then, you subtract the whole numbers and the fractions separately.
For the whole numbers: -4 - 2 = -6
For the fractions:
5/11 - 4/11 = 1/11
Combining the results, you have:
-6 1/11
wrong, its the second question of u2 l7 quick check practice
I apologize for the misunderstanding. Let me solve the correct problem for you.
To subtract mixed numbers, you need to find a common denominator for the fractions involved. In this case, the common denominator is 11.
Then, you subtract the whole numbers and the fractions separately.
-4 5/11 - 2 4/11
= (-4 - 2) + (5/11 - 4/11)
= -6 + 1/11
= -6 1/11
Therefore, -4 5/11 - 2 4/11 is equal to -6 1/11.
-6 1/11 simplifed
To simplify the mixed number -6 1/11, you can convert it to an improper fraction, if you prefer.
To convert the mixed number to an improper fraction:
Multiply the denominator (11) by the whole number (-6) and add the numerator (1). Place the sum over the denominator.
(-6 * 11 + 1) / 11 = (-66 + 1) / 11 = -65/11
Therefore, -6 1/11 simplified is -65/11.
actually the answer to the first question is -6 9/11
Apologies for the confusion. Let me solve the problem correctly.
To subtract mixed numbers, you need to have the same whole number part and the same fractional part.
Given: -4 5/11 - 2 4/11
First, subtract the whole numbers: -4 - 2 = -6
Next, subtract the fractions: 5/11 - 4/11 = 1/11
Combining the results, -6 and 1/11, we get:
-6 1/11
Therefore, the answer is -6 1/11, not -6 9/11.
12 8/5 - 7 + 7/15 + 15
To solve the expression 12 8/5 - 7 + 7/15 + 15, we need to simplify each part separately and then perform the operations.
First, let's convert the mixed number 12 8/5 to an improper fraction:
12 8/5 = (12 * 5 + 8) / 5 = 68/5
Now, let's simplify the expression:
68/5 - 7 + 7/15 + 15
To add fractions, we need to find a common denominator. In this case, the common denominator is 15:
(68/5) * (3/3) = 204/15
Now, let's add the fractions:
204/15 + 7/15 = 211/15
Finally, let's add the remaining whole numbers:
211/15 + 15
To add a fraction and a whole number, we need to convert the whole number to a fraction with a denominator of 15:
15 = 15/1
Now we can add them:
211/15 + 15/1 = (211 + 225) / 15 = 436/15
Therefore, the simplified expression is 436/15.
