Why is multiplying or dividing the numerator and the denominator by the same number the same as multiplying or dividing the fraction by 1?
Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.
How is multiplying by 10 and dividing by 2 the same as multiplying by 5?
because there the same
Could you answer Dividing a number by 2.5 is the same as multiplying a number by what?
it is the same as multiplying by 0.4
Why is multiplying or dividing the numerator and denominator by the same nonzero number the same as multiplying or dividing the fraction the fraction by 1?
Because doing so is equivalent to multiplying or dividing by x/x, which can be cancelled down to 1.
How do you determine whether a table of input output data is a function?
If every input has an output. If two outputs are the same, they must have the same input.
Is dividing by 100 the same as multiplying by 0.1?

How do you calculate the constant of proportionality?
The constant of proportionality can be calculated by dividing the output variable by the input variable in a proportional relationship. It represents the ratio between the input and output quantities in the relationship. This constant remains the same throughout the relationship.

Is taking ½ of a number is the same as dividing by ½?
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.
How is multiplying and dividing rational numbers similar?
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
How do you determine whether a table of input output data is a function?
If every input has an output. If two outputs are the same, they must have the same input.
Why is multiplying or dividing the numerator and denominator by the same nonzero number the same as multiplying or dividing the fraction by 1?
because of mathematical equivalence: it doesn't change the result
Is the input in a function table supposed to be the same as the rest of the input?
No, because then the output would be the same as the rest of the output(s).
What will be input and output current of 10 KVA 3 phase UPS?
A 10 KVA 3-phase UPS will have an input and output current that depends on the specific voltage of the system. You can calculate the current by dividing the apparent power (in this case 10 KVA) by the square root of 3 multiplied by the voltage. For example, for a 208V system, the input and output current would be approximately 28.8 amps.
