Answer 2

Problem 1: 3 8/11 + 2 6/11

To solve this problem, we need to add the two mixed numbers together.

First, let's add the whole numbers: 3 + 2 = 5.

Next, let's add the fractions: 8/11 + 6/11 = (8 + 6)/11 = 14/11.

Now, we can combine the whole number and the fraction: 5 + 14/11.

To simplify the mixed number, we can divide the numerator (14) by the denominator (11) and express the remainder as a fraction: 14 ÷ 11 = 1 with a remainder of 3. So, the mixed number is 5 3/11.

Therefore, the solution to the problem is 5 3/11.

Problem 2: 1 - 16/21

To solve this problem, we need to subtract the fraction from the whole number.

First, let's convert the whole number to a fraction: 1 = 21/21.

Next, let's subtract the fractions: 21/21 - 16/21 = (21 - 16)/21 = 5/21.

Therefore, the solution to the problem is 5/21.

Problem 3: 5 - 2 + 3/8

To solve this problem, we need to perform the addition and subtraction operations in the correct order.

First, let's subtract 2 from 5: 5 - 2 = 3.

Next, let's add the fraction: 3 + 3/8.

To add the whole number and the fraction, we need to find a common denominator. In this case, the common denominator is 8.

3 can be expressed as 24/8, so the expression becomes: 24/8 + 3/8 = (24 + 3)/8 = 27/8.

Therefore, the solution to the problem is 27/8.

Problem 4: 8 + 4/9 - 3 + 7/9

To solve this problem, we need to perform the addition and subtraction operations in the correct order.

First, let's add 8 and -3: 8 + (-3) = 5.

Next, let's add the fractions: 4/9 + 7/9 = (4 + 7)/9 = 11/9.

Now, let's add the whole number and the fraction: 5 + 11/9.

To simplify the mixed number, we can divide the numerator (11) by the denominator (9) and express the remainder as a fraction: 11 ÷ 9 = 1 with a remainder of 2. So, the mixed number is 5 2/9.

Therefore, the solution to the problem is 5 2/9.

Problem 5: 12 + 19/44 - 6 + 37/44

To solve this problem, we need to perform the addition and subtraction operations in the correct order.

First, let's add 12 and -6: 12 + (-6) = 6.

Next, let's add the fractions: 19/44 + 37/44 = (19 + 37)/44 = 56/44.

Now, let's add the whole number and the fraction: 6 + 56/44.

To simplify the mixed number, we can divide the numerator (56) by the denominator (44) and express the remainder as a fraction: 56 ÷ 44 = 1 with a remainder of 12. So, the mixed number is 6 12/44.

To simplify the fraction, we can divide the numerator (12) and the denominator (44) by their greatest common divisor, which is 4. Dividing both numbers by 4, we get 3/11.

Therefore, the solution to the problem is 6 3/11.
