16*3x+24x=.144m

solve for x, the thinkness in meters.

Non algebratic....

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?
