A carpenter uses 10 1/2 of cedar for every 6 1/3 ft of redwood for a construction project. If the carpenter uses 5 1/4 ft of cedar, how much redwood does he need?
+129840 Note : 10 + 1/2 = [21/2] and [21/2] * (1/2) = 21/4 = 5 + 1/4
So.........the amount of cedar he normally uses has been halved
......then.....the normal amount of redwood just needs to be halved, as well
So.....
6 + 1/3 = 19/3 and [19/3] * (1/2) = 19/6 = 3 + 1/6 ft of redwood
