bought?
b) How much more copper wire than
iron wire did he buy?

Answer 1

Total length of wire bought = 2 1/4 + 3 1/3

=9/4 + 10/3

=9*3/4*3 + 10*4/3*4 (LCM)

= 27/12 + 40/12

=67/12= 5 7/12metre is the answer

difference btw copper and iron wire = 40/12 - 27/12

=13/12= 1 1/12 metre of copper wire
