U can multiply
When doing fractions, you may cross 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.
if youre dealing with fractions then you multiply top by top and bottom by bottom then simplify
multiply and divide fractions!-.-
No, you cannot use models to multiply fractions!!
You multiply the fractions
Yes you do.
When you add or subtract fractions you cross multiply and when you multiply or divide fractions you across multiply.
When you divide by fractions, you invert and multiply.
yes. you multiply the numerator and denominator
The dissimilarity of the fractions doesn't matter. To multiply two fractions, multiply the numerators together, then the denominators, then put the new numerator over the new denominator. Simplify if you can. To divide fractions, invert the second fraction and multiply as just described.
Yes, there are times when you multiply fractions.
you do not do that
