Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses (Brackets)
2. Exponents (Orders and Powers)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Now let's solve the expression step by step:

1. 1 and 3/4 can be written as an improper fraction: 1 + 3/4 = 4/4 + 3/4 = 7/4
2. 7/4 * 15 = 105/4
3. -1/4 * (-16) = 4

Now, combine the results:

105/4 - 4

To simplify further, find a common denominator:

The common denominator of 4 and 1 is 4. Convert -4 to have a denominator of 4:

105/4 - 16/4

Now, subtract the fractions:

105/4 - 16/4 = 89/4

The final answer is 89/4 or 22.25.
