Bit "bighty" tonight Les?

The mat arrives as a 6x4 size= 24 square feet

The mat is now 5x3 size= 15 square feet.

I did the following in my head.

Here goes.

original = 24

Lose 9 (from 24-15)

Overall loss = 9/24

cancel down gives 3/8

1/8= 12.5%

Therefore 3/8 = 37.5%.

I agree it might not be all "loss" as I might use some of it for other purposes.

If i were doing 37% of 60% in my head.

That would be 3.7 per ten.

Thus 3.7 x 6=22.2%
