The numerator is the first nuber and the denominatoris the second.Ex. 1/2=1÷2=0.5
This is because dividing by a number is the same as multiplying by its reciprocal.
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.
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 the numerator and denominator by the same number is like dividing by 1.

because of mathematical equivalence: it doesn't change the result

The same way as multiplying a whole number by an ordinary fraction: Multiply the numerator (top number) by the whole number and put it over the original denominator (bottom number). This can then be simplified by dividing the numerator and denominator by their highest common factor; or it can be converted into a decimal (which could be a whole number) by dividing the numerator by the denominator.

Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
By dividing both the numerator and denominator by the same number is like dividing by 1.
by multiplying the denominator with the whole number and adding the numerator. the denominator will remain the same.
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.
By dividing the denominator into the numerator
Multiply the numerator and the denominator by the same number.
