(1): "7.8" was replaced by "(78/10)".
STEP 1 :
39 Simplify —— 5 Equation at the end of step 1 :
39 (3 - 10y) + —— 5 STEP 2 : Rewriting the whole as an Equivalent Fraction
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 5 as the denominator :
3 - 10y (3 - 10y) • 5 3 - 10y = ——————— = ————————————— 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:
