24.
Which of the following fraction is the largest ?
Answer: Option
Explanation:
L.C.M. of 8, 16, 40 and 80 = 80.
| 7 | = | 70 | ; | 13 | = | 65 | ; | 31 | = | 62 |
| 8 | 80 | 16 | 80 | 40 | 80 |
| Since, | 70 | > | 65 | > | 63 | > | 62 | , so | 7 | > | 13 | > | 63 | > | 31 |
| 80 | 80 | 80 | 80 | 8 | 16 | 80 | 40 |
| So, | 7 | is the largest. |

@Jyoti Mehta
We first find the lcm of the given numbers...7/8,13/16,31/40,63/80
then We'll get that value=80
So.. there goes the process and you'll get the above result...;)

No Prashant. Vidya is not correct to find the answer. Because you have to calculate all the possible values to retreive the answer. This is long process too rather than the problem explained in the beginning.

Easy way is
7/8=0.875
13/16=0.8125
31/40=0.775
63/80=0.7875
by this we can easily say dat 7/8 is the largest fraction of them.
7/8=0.875
