what is g? and explain

First, let's multiply both sides by [tex]g[/tex]. This will help to get it out of the denominator of the fraction on the right side of the equation.
[tex]g \cdot \dfrac{4840}{88} = \dfrac{1155}{g} \cdot g[/tex]
[tex]g \dfrac{4840}{88} = 1155[/tex]
To isolate [tex]g[/tex], let's multiply both sides of the equation by [tex]\frac{88}{4840}[/tex].
[tex]\dfrac{88}{4840} \cdot g \dfrac{4840}{88} = 1155 \cdot \dfrac{88}{4840}[/tex]
[tex]g = 1155 \cdot \dfrac{88}{4840}[/tex]
[tex]g = \dfrac{101640}{4840}[/tex]
[tex]g = 21[/tex]
The answer is g = 21.
