LCM and HCF
The G.C.D. of 1.08, 0.36 and 0.9 is:
Read Solution (Total 2)
-
- to find HCF
1.08=108/100;0.36=36/100;0.90=90/100;
find the HCF of numerator and LCM of denomenator hence hcf of 108,36,90=18
lcm of 100,100,100=100
therefore hcf=18/100=0.18 - 8 years agoHelpfull: Yes(1) No(0)
- for instance take them as 108, 36,90 and thier gcd is 18
and now replace it by keeping a decimal
the answer is 0.18 - 8 years agoHelpfull: Yes(0) No(0)
A website Other Question
You are given two ropes and a lighter. This is the only equipment you can use. You are told that each of the two ropes has the following property: if you light one end of the rope, it will take exactly one hour to burn all the way to the other end. But it doesn't have to burn at a uniform rate. In other words, half the rope may burn in the first five minutes, and then the other half would take 55 minutes. The rate at which the two ropes burn is not necessarily the same, so the second rope will also take an hour to burn from one end to the other, but may do it at some varying rate, which is not necessarily the same as the one for the first rope. Now you are asked to measure a period of 45 minutes. How will you do it?
Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.
