Question

А) 12,4*14,3-12,4*4,3

Answer 1

12.4 × 14.3 - 12.4 × 4.3 = 12.4 × (14.3-4.3) = 12.4× 10 = 124

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

PEMDAS/BODMAS stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction. It tells you the order in which you should perform mathematical operations.

Let's solve the expression step by step:

1. Calculate the first multiplication: 12.4 * 14.3 = 177.32
2. Calculate the second multiplication: 12.4 * 4.3 = 53.32
3. Subtract the second result from the first result: 177.32 - 53.32 = 124

So, the value of the expression is 124.
