16 similar writing pads and 24 similar jotter books are stacked in a pile. their total thickness is 14.4cm.Each writing pad is 3x as thick as each jotter book. what is the thickness of the pile of jotter books?
Please show me a non-algebraic method of solving this.Thanks
solve for x, the thinkness in meters.
total thickness=sum of thicknesses
=24T added to 16+16+16 T
= 72 T
or T=.144/72 or .02m or 2mm thick.
If you haven't had algebra, we can't
use 3x. We should say 3 times as hick as each Jotter book.
Jotter = 1/4 of the whole.
Pad = 3/4 of the whole,
1/4 + 3/4 = 4/4 = 1 Whole.
Jotter = 1/4 * 14.4 = 3.6cm.
Pads = 3/4 * 14.4 = 10.8cm.
Check: 3.6 + 10.8 = 14.4cm.
Is this what you want?
