Question

what is the length of the longest tape which can be used to measure exactly 1 metre 75 cm 4m 50 cm and 6 M 50 cm

Answer 1

The length of the longest tape is 25 cm.

Given Lengths = 1m75cm or 175 cm, 4m50cm or 450 cm, 6m50cm or 650 cm.

Now,to measure exactly 175 cm,450 cm and 650 cm with a greatest common value we need to find the GCF (Greatest Common Factor) of these three lengths.

Now,the GCF of these three lengths is simply 25.

So,the greatest common length is 25 cm.

Because,

25cm × 7 times = 175 cm

25 cm × 18 times = 450 cm

25 cm × 26 times = 650 cm

Answer 2

Answer:

25 cm

this is the right answer
