Determine the longest tape which can be used to measure 7 m,3m,85cm,12mcm95.
Find the GCF ( greatest common factor )
7 m = 700 cm = 7 ∙ 5² ∙ 2² cm
3 m 85 cm = 385 cm = 11 ∙ 7 ∙ 5 cm
12 m 95 cm = 1295 cm = 37 ∙ 7 ∙ 5 cm
7 and 5 (common to all)
Greatest common factor = 7 ∙ 5 = 35
The longest tape = 35 cm
7 m = 20 ∙ 35 cm = 20 lengths
3 m 85 cm = 11 ∙ 35 cm = 11 lengths
12 m 95 cm = 37 ∙ 35 cm = 37 lengths

To determine the longest tape that can be used to measure 7 m, 3 m, 85 cm, and 12 mcm 95, we need to compare the units and find the highest unit among them.
1. Convert everything to a common unit:
- 7 m = 700 cm (since 1 m = 100 cm)
- 3 m = 300 cm
- 85 cm = 85 cm
- 12 mcm 95 = 12.95 cm (since 1 mcm = 0.001 cm)
2. Now, we can compare the measurements:
- The highest measurement we have is 700 cm (from 7 m).
- Therefore, the longest tape that can be used should be at least 700 cm long.
So, the longest tape that can be used to measure these lengths is 700 cm.
