A tree grows 1 3/4 feet per year. How long will it take the tree to grow from a height of 21 1/4 feet to a height of 37 feet?
wow we gotta do a bunch of arithmetic here
first we need how much it grows' what is \[37-21\tfrac{1}{4}\]?
I'm asking my friend and she is telling me a lot of complicated steps, and she says the answer is some how 14?
it takes two steps, although the division will take a couple in itself
Do I have to find a common denominator?
you have to subtract is all
as a first step
you can probably compute \[37-21\tfrac{1}{4}\] in your head
like if you have thirty seven dollars and you spend twenty one and a quarter, how much money do you have left?
that equals 16
you still have to subtract a quarter
9?
ok lets go slow
you have $37 you spend $21.25 \[37-21=16\] but \[1-\frac{1}{4}=\frac{3}{4}\] so you have only \[\$15.75\] left in terms of money with fractions you have \[15\tfrac{3}{4}\]
now you have to compute \[15\tfrac{3}{4}\div1\tfrac{3}{4}\]
I have 8 whole and 4/7
