Answer 2

2/7+3/4-22/28+18/28
8/28+21/28+40/28=29/28+40/28=69/28

Answer 3

To solve the expression, let's first convert all fractions to a common denominator and then perform the operations:

Step 1: Find a common denominator for the fractions involved. In this case, the common denominator is 28 since it is a multiple of all the denominators.

Step 2: Rewrite the fractions with the common denominator:

2/7 + 3 1/4 = 2/7 + 3 + 1/4 = 2/7 + 12/4 + 1/4 = 2/7 + 13/4 = (24)/(74) + 13/4 = 8/28 + 13/4

11/14 + 18/28 = (112)/(142) + 18/28 = 22/28 + 18/28

Step 3: Perform the operations:

(2/7 + 3 1/4) - (11/14 + 18/28) = (8/28 + 13/4) - (22/28 + 18/28)

Now, we have a common denominator, so we can subtract the fractions:

= (8 + 13*7) / 28 - (22 + 18) / 28 = (8 + 91) / 28 - (22 + 18) / 28 = 99 / 28 - 40 / 28 = (99 - 40) / 28 = 59 / 28

Therefore, the result of the expression is 59/28.
