Answer 3

To solve the expression, follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, the multiplication and division should be done before the addition:

0.46 x 2.5 + 42.6 / 2.1

Step 1: Multiply 0.46 by 2.5 0.46 * 2.5 = 1.15

Step 2: Divide 42.6 by 2.1 42.6 / 2.1 ≈ 20.28571429

Now add the results of the multiplication and division:

1.15 + 20.28571429 ≈ 21.43571429

So, the result of the expression is approximately 21.44.
