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.

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.

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.

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

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.
