To find 45 divided by 9 using repeated subtraction, you should repeat by subtracting 9 every time, as the divisor is 9.
To find 45 divided by 9 by repeated subtraction, you need to subtract 9 from 45 repeatedly until you reach 0. However, you should subtract 5 every time instead of 9. Let me explain why.
When dividing a number by another number through repeated subtraction, you want to subtract the same divisor each time. In this case, the divisor is 9. The goal is to keep subtracting 9 from the dividend (45) until the dividend reaches 0.
If you initially subtract 9 from 45, you get 36.
Next, subtracting 9 from 36 gives you 27.
Continuing this process, if you subtract 9 four more times, you would end up with a negative number (-9).
However, if you subtract 5 from 45 each time, you will get the correct solution. Subtracting 5 from 45 will give you 40. Subtracting 5 from 40 will give you 35. By subtracting 5 four more times, you will reach 25.
So, to find 45 divided by 9 through repeated subtraction, you should subtract 5 from 45 each time, not 9.
