There are places where this term is used.
1st- to compare fractions across an equals you are multiplying each side by the product of the denominators. It looks like you multiply the numerator of the left side times the denominator of the right and put that product on the left side.
Multiply the numerator of the left times the denominator of the right and put that on the right. In algebra this is good when looking for an unknown.
2nd- when comparing fractions to see which one is bigger you can multiply up from the denominator to the other numerator and compare these numbers to see which one is bigger.
When cross multiplying, finding the product of the means and extremes, you are technically getting a common denominator that reduces out.
Cross-multiplying is when you have two fractions, and you multiply the numerator of each fraction by the other fractions's denominator. In other words, if you have two fractions a/b and c/d, cross-multiplying would be finding a*d and b*c. If a/b=c/d, then ad = bc.
Multiplying fractions is the easiest operation you can do with them. Nothing complicated is required, just multiply the top two and the bottom two. Simple as that!
definition of multiplying fractions?
I dont know the answer
it works when comparing fractions by multiplying the fractions to see whitch one is greater not greater and equal
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.
Multiply straight across and cross reduce when necessary
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
step by step
if you have mixed numbers you make them into improper fractions before you multiply
It is similar because when you divide fractions you are technically multiplying the second number's reciprocal. (Turning the fraction the other way around)
Multiplying fractions is quite different from adding them. You just multiply the numberators and the denominators separately. You can find the common denominator if you like, but in the end (after simplifying), you'll get the same result, and the additional work of finding the common denominator and converting the fractions turns out to be unnecessary. Try it out for some fractions!
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
