Answer 2

14 + 2/21 - 9 + 3/7

To solve this expression, we need to apply the order of operations, which is commonly known as PEMDAS (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:

First, let's simplify 2/21 and 3/7 separately:

2/21 = 0.0952 (approximately) 3/7 = 0.4286 (approximately)

Now, let's substitute these values back into the original expression:

14 + 0.0952 - 9 + 0.4286

Now, let's combine like terms:

14 - 9 + 0.0952 + 0.4286

Subtracting 9 from 14 gives us 5:

5 + 0.0952 + 0.4286

Now, let's add the decimals together:

5 + 0.0952 + 0.4286 = 5.5242

Therefore, the simplified expression is 5.5242.
