How do I convert 4 inches into yards?

4inches (1yards/36inches) = 4/36 yards

Just in case you wondered where 36 in. came from...

You must know that 1 yd = 3ft

Then you set the dimensional analysis:

the wanted is "yd".

the given is 4 in.

so... 4in.*(1ft/12in)*(1yd/3ft)=??

or 4/36 = ??

Can you see that in. cancel out,as do ft,leaving you with the wanted "yards"?

Thank you both so much!!! I get how to do it now.(:

12 in. in a foot 3feet in a yard so........ think about it!!!!
