First take LCM of denominators.
Here it s 210.
Then multiply with multiplier that makes denominators 210.
By doing this.
First becomes 70/210, 84/210 and soon.
Hence ans D.

For the first 3 options, check the first two numbers.
1/3 = 0.3333 and 2/5 = 0.4 which is in ascending order.
Hence answer is Option(D) by elimination

Tell me about the trick in this problem.
I know to multiply with hcf in the denominator and finding decending order but I think their is trick for it.
Please tell me the trick.

Converting each of given fractions into decimal form Ex: 6/7=0.85, 5/6=0.83 and so on That is the trick.
Second Method find out HCF of denominator and LCM of numerator.

Find the LCM of denominators. Then we get 210. Multiply it with current value (eg: 210*1/3 = 70) and find all values. Then you can find which one is the correct answer. Here the answer is option D.

The fastest method of solving this prblm is converting each fraction into decimal.
Instead of finding LCM, it consumes lot of time.
And as terms if fraction are easy we can solve orally in few seconds.

First take the LCM of the denominators and the LCM is 210. Which is taken to common denominator do the numerators equal to 210 by multiplying the required numbers. By comparing we get the answers.
