What is the Cross-Multiplication Calculator & How does it work?
Cross-multiplication is a method used to solve equations involving fractions. It involves multiplying the numerator of one fraction by the denominator of another and setting the products equal to each other.To solve for an unknown variable, cross-multiply and then isolate the variable. For example, if solving for a, the equation becomes: a = frac{c times b}{d}.
frac{a}{b} = frac{c}{d}
a = first numerator
b = first denominator
c = second numerator
d = second denominator
b = first denominator
c = second numerator
d = second denominator
