Detailed Solution

Here, we are given two rational numbers as

16

and

19

, and we have to determine the rational number which is exactly halfway between them.
So, the formula that we use to find such a rational number is given as,

a + b 2

, where a and b are the two given rational numbers.
So,

16 + 19 2 = 3 + 2 18 2 = 5 18 × 2 = 536

So, the rational number exactly halfway between

16

and

19

is found to be

536

.
Hence, the correct option is (1).
