Question

Поставь скобки так, чтобы получились верные записи. 405:15+12*38=483 405:15+12*38=1482 405:15+12*38=570

Answer 1

(405:15) + (12×38) =483
(405:15+12) ×38=1482
405:(15+12)×38=570

Answer 2

To make each equation correct, you need to put the correct numbers inside the brackets. Let's go through each equation:

1. 405:(15+12)*38=483 (Here, we first perform the operations inside the brackets, then do the multiplication and division from left to right.)
2. 405:15+(12*38)=570 (Here, we first perform the multiplication inside the brackets, then do the division and addition from left to right.)
3. (405:15)+12*38=1482 (Here, we first perform the division, then the multiplication inside the brackets, and finally add the two results together.)

Now all the equations are correct:

1. 405:(15+12)*38 = 405:27 * 38 = 15 * 38 = 570
2. 405:15 + (12*38) = 27 + 456 = 483
3. (405:15) + 12*38 = 27 + 456 = 483
