Answer 2

To add and subtract mixed numbers, you should first convert them into improper fractions and then perform the arithmetic. Let's break this down step by step:

1. Convert each mixed number to an improper fraction:

1 5/7 = (7 * 1 + 5)/7 = 12/7 3 11/14 = (14 * 3 + 11)/14 = 53/14 2 1/4 = (4 * 2 + 1)/4 = 9/4

2. Perform the addition and subtraction:

12/7 + 53/14 - 9/4

To add and subtract fractions, you need to have a common denominator, which in this case is 28. So, let's rewrite each fraction with a denominator of 28:

(12/7) * (4/4) = 48/28 (53/14) * (2/2) = 106/28 (9/4) * (7/7) = 63/28

Now, you can add and subtract them:

48/28 + 106/28 - 63/28 = (48 + 106 - 63) / 28 = 91/28

Now, we can simplify the fraction:

91/28 = 13/4

So, the result is 13/4, which can also be expressed as a mixed number as 3 1/4.
