Quizplus · Accepted Answer

To find how much of the nail protrudes, subtract the thickness of the board from the length of the nail: $4 \frac { 3 } { 4 }$ inches - $2 \frac { 4 } { 5 }$ inches. Convert mixed numbers to improper fractions: $19/4$ inches - $14/5$ inches. Find a common denominator (20), subtract, and simplify to get $1 \frac { 19 } { 20 }$ inches.
