Question

If you have two straight sticks of length
7:5 feet and 3.25 feet, what is the
minimum length can you measure?​

Answer 1

Given info : we have two sticks of length 7.5 feet and 3.25 feet.

To find : minimum length can be measured by these sticks.

Solution : first convert decimal into fraction.

7.5 feet = 75/10 = 15/2

3.25 feet = 325/100 = 65/20 = 13/4

Now minimum length can be measured = HCF of {15/2, 13/4}

= HCF of (15, 13)/LCM of (2, 4)

= 1/4

= 0.25

= 97.5 feet

Therefore minimum length can be measured by these sticks is 0.25 feet.
