Just need a check :)
This is from a review i'm attempting to help my daughter with, i am not a math gal by any means lol! Can anyone tell me if these are correct?
1How many 5X5" squares will fit inside a rectangle with is 25" by 35"
A.I divided 35 and 25 by 5 to get 7 and 5, then multiplied 7 and 5=35 squares
2.They say a picture is worth a thousand words. If you only paint 1/8 of a picture, how many words is it worth?
A.X=1/8(1000)=125 words
3.To maintain animals on a farm, there needs to be on acre for every foot long an animal is. If a farm has a pig which is 2 2/3ft, a horse which is 8 1/2 feet long, a cow which is 6 3/4 feet long, a goat which is 3 1/4 feet long, and an alpaca which is 4 1/2 feet long, how many acres does the farm need?
A. on this one I turned all the fractions into improper fractions, LCD for 4, and then added them all together. Then I turned my answer into a mixed fraction which gave me 25 3/4. Now this one is multiple choice and one option is actually 25 3/4 but i chose 26 as i round up to allow for a complete acre for that last 3/4 of animal lol! Does that seem right or is that 26 a trick answer?

well, 1 and 2 are fine

ganeshie8 · Answer

first two are correct. you may teach her the concept of gcd if u want, when helping her wid first question

sleepyjess · Answer

1 and 2 are correct but question 3 is unfinished.

jdoe0001 · Answer

as far as the pig.... well $\bf 2\cfrac{2}{3}\implies \cfrac{2\times 3+2}{3}\implies \cfrac{8}{3}\quad \textit{how many acres is that?}$

Sorry i just edited that question. I have no idea what I did to delete half of that problem when I submitted this. She does REALLY well, she understands the concepts better than I do (it's been awhile for me!) So really these are practice questions i have put together that I found online and don't want to give them to her to do until I know that I know how to do them myself

@MyKidzRKute    $\bf 2\cfrac{2}{3}+8\cfrac{1}{2}+6\cfrac{3}{4}+3\cfrac{1}{4}+4\cfrac{1}{2}\ \quad \\implies \cfrac{8}{3}+\cfrac{17}{2}+\cfrac{27}{4}+\cfrac{13}{4}+\cfrac{9}{2}=\cfrac{32+102+81+39+54}{12}\ \quad \
\cfrac{308}{12}\implies 25\cfrac{8}{12}\implies 25\cfrac{2}{3}$
