Question

greatest possible length which can be used to measure exactly the length 7 metres, 3 metres and 85 CM, 12, 95 cm is​

Answer 1

Answer:

The greatest length possible to measure all the given lengths exactly must be 35 cm.

Step-by-step explanation:

7m = 700cm

3m 85 cm = 385 cm

12 m 95 cm = 1295 cm

HCF of 700,385 and 1295 is 35.

700 = 35 × 5 × 2 × 2

385 = 35 × 11

1295 = 35 × 37

So to measure exactly, the greatest length we can use is 35cm.
