Answer 3

To solve this problem, you need to use the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

The problem can be written as:

3/28 - (-5/7)

To simplify this expression, we need to first remove the double negative in the second term by multiplying it by -1:

3/28 + (5/7)

Next, we need to find a common denominator for the two fractions. The least common multiple (LCM) of 28 and 7 is 28. We can convert the fractions to have a denominator of 28:

(3/28)(1/1) + (5/7)(4/4) = 3/28 + 20/28

Now that the fractions have a common denominator, we can combine the numerators:

3/28 + 20/28 = 23/28

Therefore, the solution to the expression 3/28 - (-5/7) is 23/28.
