Question 871611
<pre>
{{{6b/(14a^2)}}}{{{""=""}}}{{{"______"/(56a^4b^3)}}}

Put an {{{red(X)}}} where the blank is, and solve for {{{red(X)}}}:

{{{6b/(14a^2)}}}{{{""=""}}}{{{red(X)/(56a^4b^3)}}}

Cross-multiply:

{{{6b(56a^4b^3)}}}{{{""=""}}}{{{(14a^2)red(X)}}}

{{{336a^4b^4}}}{{{""=""}}}{{{14a^2red(X)}}}

Divide both sides by 14

{{{24a^4b^4}}}{{{""=""}}}{{{a^2red(X)}}}

Divide both sides by a<sup>2</sup>

{{{24a^2b^4}}}{{{""=""}}}{{{red(X)}}}

So

{{{6b/(14a^2)}}}{{{""=""}}}{{{red(X)/(56a^4b^3)}}}

becomes the answer:

{{{6b/(14a^2)}}}{{{""=""}}}{{{red(24a^2b^4)/(56a^4b^3)}}}
