You need to multiply by the reciprocal
which gives you
numerator: (s+t)15
denonimator: 5(2(s+t))
This will simplify to 15(s+t) over 10(s+t); which is 1.5

[(s+t)/5]/[2(s+t)/15]
= [(s+t)/5]/[2(s + t)/15]
= ((s+t)/5)(15/2(s+t)
= (s + t)[3/[2(s+t)]
= 3/2

((s + t)/5) / (2(s + t)/15)
((s + t)/5) * (15/(2(s + t)))
(15(s + t))/(10(s + t))
(3/2)

((s+t)/5)/((2(s+t))/15) =
= (15(s+t))/(10(s+t))
= 15/10
=3/2 or 1.5

try substituting nabla =s+t
nabla/5*15/2/nabla = 1.5
