Question

Mr. Diaz bought a board that was 7 feet long. He cut the entire board into pieces that were LaTeX: \frac{1}{3}1 3 foot long. How many pieces did Mr. Diaz have ?

Answer 1

Answer: Mr. Diaz will have 21 pieces.

Explanation:

Given, Length of the complete piece bought by Mr. Diaz= 7 feet

Length of each piece cut =
`\frac13` foot

By division operation,

Number of pieces = ( Length of complete piece ) ÷ (Length of each piece cut)

`=7/\frac13=7*3=21\ \ [\because a/ (b)/(c)=a*(c)/(b)]`

Hence, Mr. Diaz will have 21 pieces.
