Answer 3

Solution to the Example: (-5/16) × 1 + (7/15) + 4 + (1/5) × (-5/7)

To solve the given expression, we need to follow the order of operations (also known as PEMDAS or BODMAS). This means we need to perform the operations in the following order: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Let's break down the expression step by step:

1. (-5/16) × 1: Multiplication of -5/16 and 1 is equal to -5/16.

2. (7/15) + 4: Addition of 7/15 and 4 is equal to (7/15) + 4 = (7/15) + (60/15) = 67/15.

3. (1/5) × (-5/7): Multiplication of 1/5 and -5/7 is equal to (1/5) × (-5/7) = (-1/7).

Now, let's combine the results:

-5/16 + 67/15 + (-1/7)

To add or subtract fractions, we need to find a common denominator. In this case, the least common denominator (LCD) is 240. Let's convert all the fractions to have a denominator of 240:

-5/16 = -75/240 67/15 = 3584/240 -1/7 = -34/240

Now, we can add the fractions:

-75/240 + 3584/240 + (-34/240) = 3475/240

Therefore, the solution to the given expression is 3475/240.

Please note that the provided solution is based on the given expression and the order of operations. If there is any ambiguity or additional context, please let me know, and I'll be happy to assist you further.
