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

Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.

if you have mixed numbers you make them into improper fractions before you multiply

-4 X -4 = (+)16 Remember the table multiplying/dividing negative/positive numbers. X + = + X - = - X + = - X - = + NB If no sign is before the number, then read it as 'plus(+)'.

Cross canceling is a way to simplify or reduce fractions before multiplying them. For example, 2/4 x 1/6 can be reduced to 1/4 x 1/3 by cross canceling.

So that you can get your answer more faster and you don't need to do a lot of work

This has the effect of producing a denominator in the answer that has each of the original denominators as factors. You don't have to worry about simplifying the fractions before multiplying. Of course, you may have to simplify after multiplying. There's no way out.

In both cases, you may be able to cancel common factors, thus simplifying the expression.

That process helps to simplify your multiplication. If you have a problem such as (27/18)*4, instead of computing 27*4 then dividing that by 18 and simplifying, there is a much easier way to do it. Divide both top and bottom by 9 to get (3/2)*4. Cancel the 2 in the denominator and the 4 that is being multiplied to get 3*2. The resulting answer is 6. Notice how there were no big computations to deal with. This helps especially if you are computing all these numbers by hand or in your head.

Multiplying mixed fractions is very cumbersome and prone to errors. Therefore, it is prudent to convert them to improper fractions. Once that is done, you may simply find the product of all the numerators and divide that by the product of all the denominators. Then you convert back to a mixed number. And there are lots of tricks -- like "canceling out" -- that you can do to simplify the multiplication. Unfortunately, those techniques are very difficult to demonstrate here. It would not be even if it is not an improper fraction and that's why you have to convert

Copying its hereditary information before dividing ensures that each resulting cell receives a complete set of genetic instructions. This is essential for maintaining genetic continuity and passing accurate genetic information to the next generation. It helps prevent errors and ensures proper functioning of the new cells.

Before the nucleus starts dividing the process of DNA copying takes place

No, it is literally impossible. An equations is a question with a series of numbers which communicate by dividing, subtracting, adding, or multiplying. If we have no end to these numbers, there is an endless wave of equations coming at us, using the new number, and the infinite number before it, and after it.
