Question

The greatest possible length which can be used to measure exactly the lengths 7m, 3m85cm, 12m95cm is?

Answer 1

Answer:

0.35 m

Step-by-step explanation:

convert the meter values in cm

7m = 700 cm

3m 85cm = 385 cm

12m 95cm = 1295 cm

we need to find out the HCF of 700, 385 and 1295

700 = 2 × 2 × 5 × 5 × 7

385 = 5 × 7 × 11

1,295 = 5 × 7 × 37

common factors are 5 × 7 = 35

convert 35cm into meters 0.35 m

greatest length can be used is 0.35m
