Given that an empty box weighs 2 and 1/4 pounds.
Weight of the fruit is 16 and 2/3 pounds.
Weight of filled box means total weight of box and the fruit.
So we will add both values.
2 and 1/4 pounds+ 16 and 2/3 pounds
= 2 + 1/4 + 16 + 2/3 pounds
= 2 + 16 + 1/4 + 2/3 pounds
= 18 + 1/4 + 2/3 pounds
![= 18 + (1)/(4)+(2)/(3) \; pounds](https://img.qammunity.org/2019/formulas/mathematics/high-school/terzdqnhj92w28swrxtjwwrvbiadtv618k.png)
![= 18 + (1*3)/(4*3)+(2*4)/(3*4) \; pounds](https://img.qammunity.org/2019/formulas/mathematics/high-school/3nv9w1ay4k8g1l1auxz21nzddqbhuww6ro.png)
![= 18 + (3)/(12)+(8)/(12) \; pounds](https://img.qammunity.org/2019/formulas/mathematics/high-school/emifax5bkby6dx04k7uy81s0p2sqkwyg0c.png)
![= 18 + (3+8)/(12) \; pounds](https://img.qammunity.org/2019/formulas/mathematics/high-school/x61ns8s4jb9e59iyla1fvj1uh7pm5cjnwb.png)
![= 18 + (11)/(12) \; pounds](https://img.qammunity.org/2019/formulas/mathematics/high-school/i5lrtff6vaudlqqww9tjle73z06n3m6qdx.png)
Hence final answer is 18 and 11/12 pounds.
