Question

What proprety shows that 2/5 x 1 =40/100

Answer 1

Commutative Property.

It cannot be multiplication property because it would have to be live 5 x 1 = 5. For multiplication property the answer has to be the same as the number you used to get the answer. Does that make sense? I can send you a pic if you need it. I might be wrong because I just learned it now so I could give you an answer but from the example I got it has to be like 25x1=25, 100x1=100 something like that

Answer 2

Answer: The property is to multiplying the same constant to both the numerator and denominator i.e. 20.

Step-by-step explanation:

Since we given that

$\frac{2}{5}\times 1=\frac{40}{100}$

We need to find the property:

There is a property of making equivalent fraction by multiplying the same constant to both the numerator and denominator.

$\frac{2}{5}\times \frac{20}{20}=\frac{40}{100}$

So, the property is to multiplying the same constant to both the numerator and denominator i.e. 20.
