Clear up for the share.
To unravel for the share, it’s good to isolate the share variable on one facet of the equation.
Listed below are the steps concerned in fixing for the share:
- Multiply either side of the equation by 100.
- Simplify the equation.
- Clear up for the share variable.
For instance, as an instance now we have the next proportion:
variety of college students who handed / whole variety of college students = share / 100
We will simplify this proportion to:
variety of college students who handed / whole variety of college students = share / 100

variety of college students who handed / whole variety of college students * 100 = share
We will then simplify the equation:
(variety of college students who handed / whole variety of college students) * 100 = share
Lastly, we are able to resolve for the share variable:
share = (variety of college students who handed / whole variety of college students) * 100
This method can be utilized to calculate the share of any quantity.
Fixing for the share accurately is crucial for correct share calculations. If you’re uncertain about easy methods to resolve for the share, ask your self: “What’s the relationship between the half, the entire, the share, and 100?” Upon getting a transparent understanding of the connection between these 4 variables, you’ll be able to resolve for the share accurately.
