Conversion a mixed number 2 1/
3
to a improper fraction: 2 1/3 = 2 1/
3
= 2 · 3 + 1/
3
= 6 + 1/
3
= 7/
3
To find a new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/
3
= 6/
3
b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7
c) Write a previous answer (new numerator 7) over the denominator 3.
Two and one third is seven thirds
Conversion a mixed number 1 5/
9
to a improper fraction: 1 5/9 = 1 5/
9
= 1 · 9 + 5/
9
= 9 + 5/
9
= 14/
9
To find a new numerator:
a) Multiply the whole number 1 by the denominator 9. Whole number 1 equally 1 * 9/
9
= 9/
9
b) Add the answer from previous step 9 to the numerator 5. New numerator is 9 + 5 = 14
c) Write a previous answer (new numerator 14) over the denominator 9.
One and five ninths is fourteen ninths
Add: 7/
3
+ 14/
9
= 7 · 3/
3 · 3
+ 14/
9
= 21/
9
+ 14/
9
= 21 + 14/
9
= 35/

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(3, 9) = 9. In practice, it is enough to find the common denominator (not necessarily the
