Step-by-step explanation: The keyword is hourly. Since the keyword is hourly, the equation is division.
72 / 4
1. 4 goes into 7 once.
1a. 72 / 4 = 1
2. Now we multiply 4 by 1.
2a. 4 x 1 = 4
3. Now, we subtract 7 by 4.
3a. 7 - 4 = 3
4. Now bring down the 2.
4a. 3 = 32
5. Then you repeat the process!
We'll do the last one step-by-step!
1. 2 goes into 4, 8 times.
1a. 72 / 4 = 18
2. Multiply 8 by 4.
2a. 8 x 4 = 32
3. Lastly, subtract 32 by 32.
32 - 32 = 0
Therefore, your answer is 18 R0.
