Mark me as brainliest.
Step-by-step explanation:
Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. Then you multiply the numerator of the second fraction times the number in the denominator of your first fraction, and you write that number down.
The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater. This is especially useful when you are working with larger fractions that you aren’t sure how to reduce.
Let’s take a look at some numerical examples.
Find which of the two fractions is greatest.
426=732
So, when we cross multiply it, when we set it equal, and then cross multiply these two fractions together, we get 128. So 4×32=128. And when we cross multiply these two, we get 7×26=182. So, we know that 732 is greater than 426 because 182 is greater than 128.
