Answer 2

To solve this equation, we need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

First, we have to simplify the multiplication and division from left to right:

4 1/2 * 0.4 = 1.8 * 0.4 = 0.72

0.15 * 12 / 3 = 1.8 / 3 = 0.6

Now, we have:

0.72 : 0.6

To divide one number by another, we can multiply the first number by the reciprocal of the second number:

0.72 * 1/0.6 = 1.2

Therefore, 4 1/20,4:0,1512/3 = 1.2.
