A. Cross multiply fractions by multiplying the denominator of one fraction with the numerator of the other fraction and then comparing the two values. The fraction with the larger value is the larger fraction. *Note: Be careful to always go from denominator to numerator!

How do you solve cross multiplication method?

To find the solution of a pair of linear equations, we use cross multiplication method. If a₁x+b₁y+c₁=0 and a₂x+b₂x+c₂=0 are two linear equations, then we can find the value of x and y using this method.

Why is cross multiplying valid?

By comparing fractions using cross-multiplication, we lose the concept of finding equivalent fractions, which is ​why ​cross-multiplication works. ... This property states that if we multiply both sides of an equation or inequality by the same number, the values of each side remain equal.
