Detailed Solution

We need to find four rational numbers which are equal to 49.
To find these, we calculate and multiply the numerator and denominator with the same factors.
Multiply with 2
49 × 22 = 818
Multiply with 3
49 × 33 = 1227
Multiply with 4
49 × 44 = 1636
Multiply with 5
49 × 55 = 2045
As a result, we have four rational numbers that are equal to 49, and they are:
818, 1227, 1636, 2045.
