Put 3/8 + 1 + 5/9 over the common denominator 72. 3/8 + 1 + 5/9 = (9×3)/72 + 72/72 + (8×5)/72:

((9×3)/72 + 72/72 + (8×5)/72 12)/7

Hint: | Multiply 9 and 3 together.

9×3 = 27:

((27/72 + 72/72 + (8×5)/72)×12)/7

Hint: | Multiply 8 and 5 together.

8×5 = 40:

((27/72 + 72/72 + 40/72)×12)/7

Hint: | Add the fractions over a common denominator to a single fraction.

27/72 + 72/72 + 40/72 = (27 + 72 + 40)/72:

((27 + 72 + 40)/72×12)/7

Hint: | Evaluate 27 + 72 + 40 using long addition.
