Best shown with an example.
2 2/3 X 4 1/5
#1 Convert to improper(top heavy) fractions.
8/3 X 21/5
#2 cancel down (reduce) were possible. In this case by '3'
8/1 X 7/5
#3 multiply the numerators(top) and multply the denomiaotor(bottom) and place the numerator over the denomiator
56/ 5
#4 Convert to a mixed fraction
11 1/5 The answer. !!!
Hope that helps!!!!
When doing fractions, you may cross multiply.
U can multiply
To multiply fractions all you do is multiply the numerators and the denominators separately eg: 4/7 x 6/11 = 24/77. The "commonality" of denominators has no relevance.
To divide fractions, turn the second one over - that is, swap its numerator and denominator - and multiply. Nothing else is necessary. You cross multiply when you have a proportion, that is when you have two ratios that are equal.
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.
multiply and divide fractions!-.-
No, you cannot use models to multiply fractions!!
You multiply the fractions
When you add or subtract fractions you cross multiply and when you multiply or divide fractions you across multiply.
Yes you do.
When you divide by fractions, you invert and multiply.
yes. you multiply the numerator and denominator
Yes.
Yes, there are times when you multiply fractions.
You multiply the numerators across and put that as the numerator of your answer, then multiply the denominators of the fractions across the put that as the denominator of your answer. It is very easy.
to order fractions you can cross multiply two fractions at a time or you can convert all the fractions into decimals.
Multiply the first two together and then multiply that total by the third.
