Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
2 2 • 5
2 = — = —————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 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:
3p - (2 • 5) 3p - 10
———————————— = ———————
5 5

Equations which are never true
6.1 Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
6.2 Solve : p-6 = 0
Add 6 to both sides of the equation :
p = 6
One solution was found :
p = 6
Answer:Simplify 3/5p tp 3p/5
4 + 2p = 10(3p/5 - 2)
Expand
4 + 2p = 6p - 20
Subtract 2p from both sides
4 = 6p - 20 - 2p
Simplify 6p - 20 - 2p to 4p - 20
4 = 4p - 20
Add 20 to both sides
4 + 20 = 4p
Simplify 4 + 20 tp 24
24 = 4p
Divide both sides by 4
24/4 = p
Simplify 24/4 to 6
6 = p
Switch sides
p = 6
