exactly you got it you dont need help :)

It depends on the specific problem. If you have an equation that involves fractions, quite often you'll need to multiply them.

Fractions are multiplied by multiplying numerator by numerator and denominator by denominator. The fractions may be simplified before multiplying. Whole numbers have the understood denominator of 1. Read this lesson on multiplying fractions if you need help on how to multiply fractions.you multiply the denomanators and the top number then multiply the whole #s then reduce your answer if you can. an example would be 3 8/9X6 8/9= 18 64/81 get it now?

what fractions?

I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.

The least common factor of any set of numbers is 1, so that doesn't help at all. Finding the GCF of the numerator and denominator and dividing them by it will help to simplify a fraction. Finding the least common multiple of the denominators (called the least common denominator) will help when you add and subtract fractions. None of those are needed to multiply fractions.

To add and subtract unlike fractions, find the LCM of the denominators and convert them to equivalent like fractions. You don't have to do anything to fractions to multiply them, but you may need to reduce one after multiplying. To do that, find the GCF of the numerator and the denominator and divide both of them by it. If the GCF is 1, the fraction is in its simplest form.

Fractions help with numbers that are not whole numbers.

When adding and subtracting unlike fractions, it is necessary to find the LCM of the denominators, called the least common denominator. Once you have found the LCD, you can convert the fractions to equivalent fractions with a common denominator and proceed with the adding and/or subtracting. Finding an LCM will have no effect on multiplying fractions.

There is a game specifically designed for understanding how to divide and multiply fractions. It can be found at ellerbruch.nmu.edu.

Knowing the LCM of the denominators will help you to find a least common denominator of unlike fractions, which will allow you to add and subtract them successfully. Knowing the GCF and LCM will not help you in multiplying them, but knowing the GCF of the numerator and denominator of a fraction will help you reduce it if necessary.

Knowing the LCM will help when adding or subtracting unlike fractions. By finding the LCM of the denominators, (called the lowest common denominator) you can convert unlike to like fractions and proceed with the adding or subtracting. Knowing the GCF helps reduce a fraction. By finding the GCF of the numerator and the denominator and dividing both of them by it, you can reduce a fraction to its lowest terms (simplest form). If the GCF is 1, the fraction is in its simplest form. You can successfully multiply fractions without knowing the GCF or LCM.

The LCM will help you add and subtract fractions. The GCF will help you simplify fractions.
