**MathMate**, Thursday, December 2, 2010 at 11:35amDo the subtraction like a normal (numerical subtraction) with borrowing. The only difference is when you borrow, you don't always get 10 from the next digit, but the appropriate number from the next

*unit*.

For example,

4yd 2ft 4in - 3yd 1ft 9in

Put them one on top of the other if you wish:

4yd 2ft 4in

3yd 1ft 9in

4in - 9in , we need to borrow to get 1ft+4in=16in

so 16in - 9in = 7in.

4yd 2ft 4in

3yd 1ft 9in

------------

?yd ?ft 7in

Now 2ft on top becomes 1ft (after borrow), so 1ft-1ft =0ft

4yd 2ft 4in

3yd 1ft 9in

------------

?yd 0ft 7in

Finally, 4yd - 3yd = 1 yd

4yd 2ft 4in

3yd 1ft 9in

------------

1yd 0ft 7in

Proceed this way for your problem, and post for answer check if you wish.
