Andy has 12 feet long strange she will cut the string into equal links of 5 inches each how much during will be left after she cut as many of the launch as possible

Well, there are 12 inches in a foot so there are 144 inches in 12 feet of string. 144 divided by five is 28 (rounding down the 140 not 144) There will be 4 inches left of the string after he cut as much of the string I could.
