Ответ:



Let's solve these multiplication problems step-by-step:



1. 249 * 42


First, multiply 249 by 2 (the ones digit of 42):


249 * 2 = 498


Next, multiply 249 by 40 (the tens digit of 42):


249 * 4 = 996, so 249 * 40 = 9960


Finally, add the two results together:


498 + 9960 = 10458


Answer: 10458



2. 508 * 125


First, multiply 508 by 5 (the ones digit of 125):


508 * 5 = 2540


Next, multiply 508 by 20 (the tens digit of 125):


508 * 2 = 1016, so 508 * 20 = 10160


Then, multiply 508 by 100 (the hundreds digit of 125):


508 * 100 = 50800


Finally, add the three results together:


2540 + 10160 + 50800 = 63500


Answer: 63500



3. 608 * 27


First, multiply 608 by 7 (the ones digit of 27):


608 * 7 = 4256


Next, multiply 608 by 20 (the tens digit of 27):


608 * 2 = 1216, so 608 * 20 = 12160


Finally, add the two results together:


4256 + 12160 = 16416


Answer: 16416



4. 953 * 74


First, multiply 953 by 4 (the ones digit of 74):


953 * 4 = 3812


Next, multiply 953 by 70 (the tens digit of 74):


953 * 7 = 6671, so 953 * 70 = 66710


Finally, add the two results together:


3812 + 66710 = 70522


Answer: 70522
