Answer 3

To solve the expression (14 - 2 11/12 : 7/18) 4 7/8, we need to follow the order of operations (also known as PEMDAS/BODMAS). PEMDAS stands for 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:

Step 1: Simplify the division within the parentheses. (14 - 2 11/12 : 7/18) 4 7/8 First, let's convert the mixed number 2 11/12 into an improper fraction: 2 11/12 = (2 * 12 + 11) / 12 = 35/12

Now we have: (14 - 35/12 : 7/18) 4 7/8

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction: 35/12 : 7/18 = 35/12 * 18/7

Now we can simplify the division: 35/12 * 18/7 = (35 * 18) / (12 * 7) = 630/84 = 15/2 = 7.5

Step 2: Substitute the division result back into the expression. (14 - 7.5) 4 7/8

Step 3: Simplify the subtraction inside the parentheses. 14 - 7.5 = 6.5

Now we have: (6.5) 4 7/8

Step 4: Multiply 6.5 by 4. 6.5 * 4 = 26

Now we have: (26) 7/8

Step 5: Multiply 26 by 7/8. 26 * 7/8 = (26 * 7) / 8 = 182/8 = 22 3/4

Therefore, the expression (14 - 2 11/12 : 7/18) 4 7/8 equals 22 3/4.
