:
Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 2 as the denominator :
2a 2a • 2
2a = —— = ——————
1 2
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 :
3.2 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:
2a • 2 - (a2) 4a - a2
————————————— = ———————

:
Rewriting the whole as an Equivalent Fraction
6.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 3 as the denominator :
2a 2a • 3
2a = —— = ——————
1 3
Adding fractions that have a common denominator :
6.2 Adding up the two equivalent fractions
2a • 3 + a 7a
—————————— = ——
