Answer:
It's not correct
Because
Ratio is the comparison of two quantities having same units
So this ratio can't be taken
D = rt
/r /r
D/r = T
*sample text*
#42.
14n - 32 = 22
add 32 to both sides
14n - 32 + 32 = 22 + 32
simplify
14n = 54
divide both sides by 14
14n/14 = 54/14
simplify
n = 3 12/14
n = 3 6/7 or n = 3.857
