A unit vector in the direction of a would be the vector a multiplied by a factor such that the length of vector a is unity.
The magnitude of a is given by:
|a|
=sqrt(4^2+3^2+2^2) [ I got lazy instead of writing (-4)^2+(-3)^2+2^2]
=sqrt(29).
So the univector is a/sqrt(29), or (-4/sqrt(29),-3/sqrt(29), 2/sqrt(29), or simply (-4,-3,2)/sqrt(29).
Since its 3/4 serving and there are 18 pancakes
18 divided by 3/4
just find the reciprocal (switch the denominator and numerator) and change divide to multiply
18 x 4/3 = 24 servings
the reason being for multiplying the reciprocal: there is a rule stating that whenever you divide something by a fraction, you change the divide sign to a multiplying sign and flip the flip the digits in the numerator and denominator section in the fraction (basically the fractions reciprocal)
or another way of doing it is
3/4 = 0.75
18/0.75 = 24
but you'll likely to need a calculator for that
