Answer: 478 1/2
Step-by-step explanation: 3 ft 3 7/8 in. is 39 7/8 in. 39x12=468. 7/8x12=84/8 or 10 1/2. 468+10 1/2=478 1/2.
The total length needed in inches is [tex]478 \frac{1}{2} [/tex].
Given that,
- A machinist must cut 12 strips of metal that are each 3 ft 3 7 by 8 in. long.
Based on the above information, the calculation is as follows:
[tex]= 3\ 3 7\div 8 \\\\ = 39 7\div 8 [/tex]
Now
[tex]= 39\times 12=468\\\\ = 7\div 8\times 12 = 84\div 8 or 10\ 1 \div 2 \\\\ = 468+10 1\div 2=478\ 1\div 2.[/tex]
