Well first you have to find the least common multiple (LCM)...
90
: 90 180 270 360
450
540 630 720 810 900
150
: 150 300
450
600 750 900
Now you notice that they both have
450
in common and it's the LEAST common multiple unlike 900 which is the MOST.
After that they have to be rewritten with 450 as their denominator.
35/450
and
357/450
are your answers

LCM( 90, 150)= 2*3^2* 5^2= 450
Therefore,
the least common denominator of 7/90 and 119/150 is 450
