Answer:
He has 4 10/12 wire left
Step-by-step explanation:
The common ratio is the current number divided by the previous. So the ratio is 1/2
The sequence is 12, 6, 3, 3/2, 3/4 ...
You can obtain any number multiplying the previous number times 1/2.
6 = 12 *(1/2)
3 = 6*(1/2)
3/2 = 3*(1/2)
3/8 divided by 4/5 is the same as 3 * 5 / 8 * 4 = 15/32 or 0.46875
