Which longest tape can be used to measure exactly the length 7m, 3m 85...
Explanation:

Given Lengths:
- 7m = 700 cm
- 3m 85cm = 385 cm
- 12m 95cm = 1295 cm

Finding the Greatest Common Divisor (GCD):
To find the longest tape that can measure all three lengths exactly, we need to calculate the Greatest Common Divisor (GCD) of the three lengths.
- GCD of 700, 385, and 1295 = 35

Choosing the Longest Tape:
The longest tape that can measure all three lengths exactly is the tape that has a length equal to the GCD of the given lengths.
Therefore, the longest tape that can measure exactly the lengths 7m, 3m 85cm, and 12m 95cm is 35 cm.

Correct Answer: 35 cm
