add and subtract fractions?

During certain jobs people need to be able to add and subtract fractions to build or make things. With out being able to add or take away, we would have a harder time completing a project.

How they use fractions? They use it to help with accuracy. While

Building things need to be precisely measured and cut. The larger the denominator the more accurate the cut needs to be.

Also putting more than one piece together the fractions need to be added.

Why are they important? Fractions are important because they

create a set of standards for the carpenters. Buildings, houses, decks, and etc. need to be cut and put together with the right measurements to be correctly put together so it is not unstable.

It is a hazard is the measurements are not correct. Injury could occur.

If we did not have fractions…. There would be a harder time dividing

and finding percentage, if it would even be possible.

All carpentry work would have to be in whole numbers, meaning things would not fit exact.

There would not be portions or decimals.

Interesting facts “a fraction is nothing more than a form

of division and can be converted to decimals at will.” (VMS forum)

In carpentry the cutting of the wood and measuring also incorporate geometry.

Egyptians were the first found use fractions in 1800 b.c.
