I'm pretty sure its two.
(-1/5)
-2 (negative two) The multiplicative inverse (reciprocal) for a number x is 1/x.
3 and a half = 7/2 so its multiplicative inverse is 2/7.
Multiplying by 1 and a half.

Since subtraction is the inverse function of addition, the additive inverse of one half is minus one half.

Mathematically, an inverse is an opposite, it is something that reverses what its inverse does, for example, addition and subtraction are inverse functions, as are multiplication and division. The inverse of a fraction is obtained by exchanging numerator and denominator; the inverse of a half is two.
(1/2) / (1/16) = (1/2) * (16/1) division equals multiplication by the inverse and the inverse of 1/16 is 16/1.= 16/2 = 8Another way to look at it is: 16 sixteenths make one. So half of them make a half ie 8 sixteenths make a half.

The clock out frequency of an 8085 is one half the crystal frequency. The period of one T cycle is the inverse of the clock frequency. At a crystal frequency of 5MHz, the clock is 2.5MHz, and T is 400 ns.
