​

Answer 1

Answer:

- 14580

Step-by-step explanation:

Given : use convenient grouping to find  18 x (-27) x 30. here we can group positive numbers on one side and the negative number on the other side for our convenience. So we get

        (18 x 30) x (- 27)

           ( 540 ) x (- 27)

           - 27 x 540

        = - 14,580

After solving we get the answer as - 14,580
