2 : 14 is equal to 98 : 686.
An easy way is to get an equivalent ratio is to round it down as much as possible. 2:14 can be rounded down to 1:7, as both sides can be divided by 2 (think ratios like fractions).
Then, just multiply BOTH sides of the ratio by the same number. With 2:14, you multiply 2 by 49 (since 2 times 49 is 98) and multiply the other side by 49.
49 × 14 is 686.
So the equivalent ratio of 2:14 starting with 98 is 98:686.
Hope it helps!!
