One way to understand division is to look at it as repeated subtraction. When you "divide by" a divisor number, you're asking "how many times can I subtract this divisor from the dividend, before the dividend is all used up ?".
Well, if the divisor is ' 1 ', then you're taking ' 1 ' away from the dividend each time, and the number of times will be exactly the same as the dividend.
If the divisor is more than ' 1 ', then you subtract more than ' 1 ' from the dividend each time, and the number of times you can do that is less than the dividend itself.
If the divisor is less than ' 1 ', then you only take away a piece of ' 1 ' each time. You can do that more times than the number in the dividend, because you only take away a piece each time.
Sixth grade Because if you divide their total profit by the total amount of hours they worked, you would find that the sixth grade's income per hour is the highest. Sixth grade: 170÷5=34 Seven grade: 112÷4=28 Eighth grade: 192÷6=32
