Question

How many pieces of 3.2m length can be cut from a steel rod of 287.5m?

Answer 1

Answer:

89

Step-by-step explanation:

$Let \ the \ number \ of \ pieces \ be \ 'n' \\\\ Length \ of \ each \ piece,l=3.2 \ m \\\\ Total \ length \ of \ steel \ rod,L=287.5 \ m \\\\\\ =>nl = L \\\\ => n(3.2)=287.5 \\\\=>n=\frac{287.5}{3.2} \\\\=>n =89 \\\\ 89 \ pieces \ of \ length \ 3.2 m \ can \ be \ cut \ from \ a \ steel \ rod \ of \ 287.5 \ m$
