Answer:
144
First lets organize out 4 possibilities of vowels (V) vs consonants (C)
VCVCVC, VCVCCV, VCCVCV, CVCVCV
Now within those 4 combinations there are 6 ways to order the 3 consonants
RNG, RGN, GRN, GNR, NRG, NGR
And likewise 6 ways to order the 3 vowels
OAE, OEA, EAO, EOA, AEO, AOE
So in total there are 6*6*4=144 different ways to arrange the letters of ORANGE so that none of the vowels are next to eachother.
