Question

Look at the table. Write the number and the operations in each machine.

1) 840, ÷ 20
2) 800, ÷ 20
3) 760, ÷ 20
4) 720, ÷ 20

Answer 1

The question involves division of a series of numbers by 20. Each number (840, 800, 760, 720) should be divided by 20 to get the result, which would be 42, 40, 38, and 36 respectively.

Step-by-step explanation:

The student's question involves performing division on a series of numbers. Each operation provided in the student's list involves dividing the starting number by 20. To solve these operations, simply enter the starting number into a calculator and then divide by 20. The calculations should be rounded to four decimal places if necessary. Here's a step-by-step example for the first operation:

1. Start with the number 840.
2. Divide 840 by 20.
3. The result is 42 after division.

Repeat the same process for the other given numbers (800, 760, and 720) to get their respective results after division by 20. For the other numbers in the sequence, you would perform the same division, which would yield 40 for 800, 38 for 760, and 36 for 720.
