Please help me answer this problem. Thank you so much If n is directly proportional to the cube of m and that n = 27 when m = 1 1/2, find: a) the value of n when m = 2 d) the value of m when n = 125

Use n = 27 when m = 1 1/2 to get the value of k. Then use your formula to answer a) and d). If you need more help, please show all your work and say where you're stuck.
