a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally 2 * 4/
4
= 8/

b) Add the answer from previous step 8 to the numerator 1. New numerator is 8 + 1 = 9
c) Write a previous answer (new numerator 9) over the denominator 4.
Two and one quarter is nine quarters
Add: 1/

= 1 · 4/
3 · 4
+ 9 · 3/
4 · 3
= 4/

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, 4) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - one third plus nine quarters = thirty-one twelfths.
