Question

A horseshoe weighs 8.2 ounces. The nails make up 0.2 of that weight. What is the weight of the horseshoe without the nails?

Answer 1

8.2 Ounces because it says a HORSESHOE Weighs.  They threw in the nails weight to throw you off.

Answer 2

8.2=82/10

0.2=1/5

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

1/5*82/10=82/50

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

82/10-82/50

=820/100-164/100

=656/100

=6.56

Answer: 6.56 ounces
