Find the greatest possible length that can be used to measure exactly the lengths 8 m 75 cm, 1.75 m, and 12 m 20 cm.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 5 cm.
⇒ 8 m = 800 cm
⇒ 75 cm
⇒ 1.75 m = 175 cm
⇒ 12 m = 1200 cm
⇒ 20 cm
HCF of (800, 75, 175, 1200, 20) = 5
So,
The greatest possible length which can be used to measure exactly the lengths 8 m, 75 cm, 1.75 m, and 12 m, 20 cm = 5 cm
