He spent 12 hours studying science.
The ratio of time Jerome spends on math and science, respectively, is 4:3. We know he spent 16 hours studying math last week, so our proportion looks like:
4/3 = 16/x
Cross multiply:
4*x = 3*16
4x = 48
Divide both sides by 4:
4x/4 = 48/4
x = 12
Since Jerome and Ross spent the same amount of time on science, then Ross also spent 12 hours on science.
