Tom is working on a woodworking project at home. he is building a table and needs five even pieces 3/5 of a foot long and you cut a 2 1/4 feet long piece from a 4 foot piece already does tom have enough wood to finish his project

Lets convert our quantities to decimal form first:
3/5 of a foot is 0.6 foot. Since he need five equal pieces of that length, he needs  feet to build his project.
2 1/4 feet is 2.25 feet. So, he now has two pieces one of 2.25 feet long and another one of  feet long.

Next, lets find if he has enough wood for his project:
From the 2.25 feet piece he can cut ; since he needs even pieces, we can discard the decimal part of the result; therefore, he can cut 3 pieces.
From the 1.75 piece he can cut ; similarly, since he needs even pieces, we can discard the decimal part of the result; therefore, he can cut 2 pieces.
From both pieces, he can cut 2+3=5 pieces.

We can conclude that he has enough wood left to finish his project.
