Math breakthrough!!
gruvystarchild
No, not one of my kids, ME! Yep, had a math moment last night...it
was really cool.
I am in the process of desiging a weathering area/mews for my hawk
(no, don't have the bird yet. Permit and weathering area comes
first)....which involves some math skills I just don't have.
I was trying to draw a to scale design, asking dh for some pointers.
Well, because I'm doing the roof at a slant, to allow rainwater to
run off, I was trying to figure out how on earth I'd know what length
lumber to buy.
If I put the base of the structure ten feet wide, I figured the slant
on the roof would make it longer than ten feet since it's at an
angle...what to do?
Dh showed me a formula for figuring out the unknown side of a
triangle and we calculated that by dropping one foot from front to
back of the structure, it would only change the length by less than
an inch....drop it two feet and it would change by over 2 inches.
I did a formula!! whoohooooo....
Anyway, that led to my wanting to know how to change fractions to
decimals, decimals to fractions and a lot of other stuff I could not
remember. Sad eh?
I need Pam now though, because I am stumped on an equation. I figured
out how to change 7/12th's to a decimal (.5833) but how to show the
steps of changing it from decimal form to a fraction? I can't do it.
.5833/1,000 is how you would start, right? How do you solve this when
you can't find a common denominator?
What are the steps? I can't find a common denominator for these two
numbers and get it to the 7/12ths that I know is the answer.
How do you get this to 7/12ths? HELP!!
I am so happy to know I'm not a total idiot, just Math phobic....

Ren,
You could also have measured your drawing and multiplied by scale. If your
drawing showed four inches to four feet... that would be easy!
But with lumber and roofing materials there's no sense figuring it out to the
inch because lumber and tarpaper and stuff only come in certain sizes. You
put it on and cut off the extra.
Sometimes too much math isn't necessary.
