a) Multiply the whole number 8 by the denominator 6. Whole number 8 equally 8 * 6/
6
= 48/
6
b) Add the answer from previous step 48 to the numerator 4. New numerator is 48 + 4 = 52
c) Write a previous answer (new numerator 52) over the denominator 6.
Eight and four sixths is fifty-two sixths
Conversion a mixed number 5 8/
12
to a improper fraction: 5 8/12 = 5 8/
12
= 5 · 12 + 8/
12
= 60 + 8/
12
= 68/

To find new numerator:
a) Multiply the whole number 5 by the denominator 12. Whole number 5 equally 5 * 12/
12
= 60/
12
b) Add the answer from previous step 60 to the numerator 8. New numerator is 60 + 8 = 68
c) Write a previous answer (new numerator 68) over the denominator 12.
Five and eight twelfths is sixty-eight twelfths
Subtract: 52/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 12) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 12 = 72. In the next intermediate step, , cancel by a common factor of 12 gives 3/
