Answer 2

To solve the expression 0.4 / 0.3 : 1 / 2, you should follow the order of operations (PEMDAS/BODMAS):

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

Let's break down the expression step by step:

Step 1: Division 0.4 / 0.3 = 1.333333... (repeating decimal, which can be rounded to 1.33)

Step 2: Division 1 / 2 = 0.5

Step 3: Divide the results of Step 1 and Step 2 1.33 / 0.5 = 2.66 (rounded to two decimal places)

So, the correct answer is approximately 2.66.

Now, let's check the provided options:

1. 2 with a remainder of 2/3 (2 2/3 as a mixed number)
2. 4.4
3. 4

The correct answer is not among the options given, as the actual result is approximately 2.66.

To calculate it manually: 0.4 / 0.3 = 1.33 (rounded) 1.33 : 0.5 = 2.66 (rounded)

So, the answer is 2.66.
