To find the product of two fractions, you simply multiply across top & bottom. But first, you can see that 12 and 15 have a common factor of 3. So, (11 / 15) * (12 / 7) then becomes: (11 / 5) * (4 * 7) Multiplying straight across, you get: (11 * 4) / (5 * 7) = 44 / 35

If you're talking about the median, then you're missing a number in your list. Your list is: 1400, 1550, 1700, 2500, 7000 which has 5 numbers. The median (the middle number) would be the 3rd, which in this case is 1700. If you want the median to be [(1700 + 2500) / 2] ...

If both terms are equal, that is: x / 60 = 9 / 5 Then, x is to 9, as 60 is to 5. 60 = 5 * 12 so, x = 9 * 12 thus, x = 108.
