Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
it is the same as multiplying by 0.4
No. By definition, 20% is equal to 0.2. Multiplying a number by 0.2 is not equal to dividing it by four. Finding 25% of a number is equal to dividing that number by 4. Finding 20% of a number is equal to dividing that number by 5.
This is because dividing by a number is the same as multiplying by its reciprocal.
No, taking ½ of a number is the same as dividing it by 2. Dividing a number by ½ is the same as multiplying it by 2.

No. Taking one half of a number is the same as dividing it by 2. If you divide a number by 1/2 that's the same as multiplying it by 2.
it is the same as multiplying by 0.4
the number would stay the same
No. By definition, 20% is equal to 0.2. Multiplying a number by 0.2 is not equal to dividing it by four. Finding 25% of a number is equal to dividing that number by 4. Finding 20% of a number is equal to dividing that number by 5.
This is because dividing by a number is the same as multiplying by its reciprocal.
Dividing a number by 100 is the same as multiplying that number by 0.01. This operation effectively shifts the decimal point two places to the left. For example, dividing 250 by 100 results in 2.5, which is equivalent to multiplying 250 by 0.01.
That is the definition of reciprocal.
Yes, it is!:)
