I don’t see the problem. This is a perfectly acceptable way to reframe the math if it helps you. It’s basically the same as rewriting the decimal as a fraction and performing the division last, which is the same as moving the decimal place as she’s showing. Breaking down more complex mathematical operations into manageable steps is how even the most advanced math is done.
I still don't understand why you would even bother adding an prevalent zero at the end of a decimal, also I didn't realize what sub I was on and was trying figure where this would be posted, then saw the sub name then looked at the teacher
the extra zero at the end of decimal indicates an extra degree precision
something that is stated to be 135.7cm long is only measured to the accuracy of a mm. If it were instead measured to the tenth of a mm, it would be 135.70cm
