There is a rule that the numbers on both sides of the division sign are multiplied (divided) by the same number at the same time, and the result of division remains unchanged.

For example, 132 ÷ 1 can be converted into 1320 ÷ 1. Multiply both sides of it by 10 and the result is the same.

Similarly,1.32 ÷ 0.01can be converted into 1320÷ 1 1, and both sides are multiplied by 1000.

Take 10.24÷0.0 16 as an example, the formula will be deformed. I think you've thought of it. Yes, the original formula will be converted into 10240÷ 16.

it is quite easy to do so.

Decimal divided by decimal (both divisor and dividend are greater than zero)

Decimal divided by decimal (both divisor and dividend are less than zero)?

Decimal divided by decimal (dividend with divisor less than zero is greater than zero)

Decimal divided by decimal (dividend is less than zero and greater than zero)? You're not talking about the problem. Pay attention to the deformation.

I made a picture myself and send it to you now. . . . .
