He irons 5/81 of his shirt in 1 minute.
Since he irons 2/9 of his shirt in 3 3/5 minutes, we divide 2/9 by 3 3/5 to find the portion done in 1 minute:
2/9 ÷ 3 3/5
Convert the mixed number to an improper fraction:
2/9÷18/5
Flip the second fraction and multiply:
2/9×5/18
= 10/162
Simplifying, we have 5/81.
