<span>Step 3 :</span>Rewriting the whole as an Equivalent Fraction :
<span> 3.1 </span> Subtracting a whole from a fraction
Rewrite the whole as a fraction using <span> 5 </span> as the denominator :
-15 -15 • 5
-15 = ——— = ———————
1 5
<span>Equivalent fraction : </span>The fraction thus generated looks different but has the same value as the whole
<span>Common denominator : </span>The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
<span> 3.2 </span> Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
(p+10) - (-15 • 5) p + 85
—————————————————— = ——————
5 5
<span>Equation at the end of step 3 :</span> p + 85
—————— = 0

<span>Step 4 :</span>When a fraction equals zero :<span><span> 4.1 </span> When a fraction equals zero ...</span>
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the <span>denominator, </span>Tiger multiplys both sides of the equation by the denominator.
Here's how:
p+85
———— • 5 = 0 • 5
5
Now, on the left hand side, the <span> 5 </span> cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
p+85 = 0
Solving a Single Variable Equation :
<span> 4.2 </span> Solve : p+85 = 0<span>
</span>Subtract 85 from both sides of the equation :<span>
</span> p = -85
One solution was found : <span> p = -85</span>
