(3/4) x (5/9) = (3x5)/(4x9) = 15/36, that is when you multiply fractions, you multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result

(3/4) / (5/9) = (3/4) x (9/5) = 27/20, that is when you divide fractions, you first invert the fraction by which you are dividing and then multiply the numerators and form the numerator of the result and multiply the denominators and form the denominator of the result

No you do not.

Yes. When multiplying and dividing fractions your denominators do not have to be the same. The denominators only haveto be the same if you are subtracting or adding them.

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.

You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.

Details about multiplying and dividing rational number involves modeling multiplying fractions by dividing squares to equal segments and then overlap the squares.

When you're dividing fractions ... or multiplying thrm ... they don't need to have the same denominator.

"of" means multiply, i think.

This is because dividing by a number is the same as multiplying by its reciprocal.

It is similar because when you divide fractions you are technically multiplying the second number's reciprocal. (Turning the fraction the other way around)

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

Same as adding, multiplying, and dividing.
