Numerator = 941941 Denominator = 1000000.

Yes. If the numerator (on top) is higher or equal to the denominator (bottom) than its an improper fraction. If the numerator and denominator are the same then the fraction is considered a whole number and always comes out 1. If the numerator is higher than the denominator then you must divide the numerator by the denominator.

That would be the numerator. The numerator is above the denominator. The numerator divided by the denominator would be equal to the quotient. So, numerator/denominator = quotient

It can be any whole number. You really can't calculate the numerator based on the denominator.

You would normally start by multiplying both sides of the equation by whatever is in the DENOMINATOR (the bottom part of the fraction), to get rid of fractions.

Dividing a friction is multiplying by its reciprocal. The reciprocal of a fraction is the numerator and the denominator switched around.

by dividing the numerator by the denominator

Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.

Because doing so is equivalent to multiplying or dividing by x/x, which can be cancelled down to 1.

Yes. One method for dividing fractions is to multiply the numerator fraction by the reciprocal of the denominator fraction.

Dividing the numerator and denominator by a common factor is how you simplify a fraction.

123.456 is changed into fraction by multiplying and dividing it by a number such that both denominator and numerator don't contain decimal. Multiplying and dividing by 100, we get 123.456 as 123456/100.

by dividing both numerator and denominator

You will get a rational fraction.

By dividing both the numerator and denominator by the same number is like dividing by 1.

The terms of a fraction are 'Numerator' and 'Denominator.' The numerator is the number atop the dividing line, the denominator is that on the bottom. For example, in 5/7, five is the numerator, and seven is the denominator.

That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct.
