Answer 1

Answer:

infinite long it can be

Answer 2

Answer:

35cm

Explanation:

convert all in same units(cm)

7m = 700m

3n 85cm = 385cm

12m 95cm = 1295cm

now GCD( 700, 385, 1295)

use division method GCD(700,385) = 35

again GCD ( 35, 1295) = 35

therefore GCD( 700, 385, 1295) = 35

hence the longest tape = 35cm
