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. |

(7/8)*10 = 70/80;
(13/16)*5 = 65/80;
(31/40)*2 = 62/80;
(13/16)*5 = 65/80;
(31/40)*2 = 62/80;

Lcm is
8 16 40 80.
Factor is 2 * 2 * 2 * 5 * 2 = 80.
8 16 40 80.
Factor is 2 * 2 * 2 * 5 * 2 = 80.
