Question

75 devided by 1 1/8

Answer 1

do you have a calculator? :)

Answer 2

if so, you need to type in your calculator 75/1.125

Answer 3

yes i have a caculator but i do not know hoow to enter it into my calculator to get the answer

Answer 4

75 divided by 1 1/8 =
75 divided by 9/8 =
75/1 x 8/9 = 600/9 = 66 6/9 = 66 2/3

Answer 5

i dont know how to put that fraction in my calculator either

Answer 6

well, anytime you want to convert a fraction into a decimal, all you have to do is divide it! for example 1/8 would be one divided by 8. that gives you 0.125. +1, obviously. so you have to type in your calculator
75 divided by 1.125 :)

Answer 7

the answer you will get is a decimal that is a very easily recognizable fraction. let me know what you get and if you need help converting it back. :)

Answer 8

okay thanks

Answer 9

hold on , im gonna type the question im trying to find out

Answer 10

tonys club is selling oranges to raise money. for every box they sell, they get 1 1/8 dollars profit. they have sold 75 boxes already. how many more boxes must they sell to raise 180 dollars?

Answer 11

oh, division is not going to help you here. You need to multiply!

Answer 12

75 * 1.125 = ?

Answer 13

is that all i do is multiply that

Answer 14

no, that's the first step.

Answer 15

\[\frac{75}{1\frac{1}8}\]First convert \(1\frac{1}8\) to a fraction by multiplying the denominator of the fraction times the whole number and adding that to the numerator:
\[1\frac{1}{8} = \frac{8*1+1}{8} = \frac{9}{8}\]Next, rewrite the division by making it a multiplication by the reciprocal of the divisor. Reciprocal is just fancy language for "turn that sucker upside down" :-)

\[\frac{75}{1\frac{1}{8}}=75*\frac{8}{9} = \frac{75*8}{9}=\frac{600}{9}=\frac{200}{3}\]At this point, if you want to make a mixed number, divide 200/3 and take the whole part as the number, plus the leftover part over 3 as the fraction: 200/3 = 66 with a remainder of 2, so the mixed number would be \(66 \frac{2}3\).

Answer 16

whats the second step lol

Answer 17

I agree that division isn't what you need to be doing in this problem...

Answer 18

take that answer, which should be 84.38, and subtract it from 180.

Answer 19

i got 95.62

Answer 20

after subtracting the two numbers

Answer 21

correct. now you have to find out how many boxes you'd have to sell to make that much. Do you have any idea what you'd do to find that out?

Answer 22

not reeally

Answer 23

Another way to approach the problem:

When they sell a box of fruit, they get $1 1/8 profit. To get $180 profit, they need to sell \[$180 / ($1 1/8) = \frac{180}{\frac{9}{8}}\] boxes in all. If we can do that division, we can easily subtract off the number of boxes already sold.

\[\frac{180}{\frac{9}{8}} = 180 *\frac{8}{9}\]We can easily divide 180 by 9 and multiply the result by 8 to get the total number of boxes to sell for $180 profit.

Answer 24

That "$11/8" should have been $1 1/8, helpful LaTex, ever my friend...

Answer 25

alright, well each box gives them 1.125. they need 95.62. so you need to divide 95.62 by 1.125 to find out how many boxes they still need to sell.

Answer 26

whpalmer4 i did what u said and got 160 and it was wrong.

Answer 27

That's the *TOTAL* number of boxes to sell to get $180 profit. They've already sold 75, remember, so the answer is 160-75 =

Answer 28

you should end up with 84.9955555555..... which can round to a nice, easy, 85 boxes. :)

Answer 29

No rounding required with my method.

Answer 30

oh okay my bad. thanks the both of u

Answer 31

and if you do what @whpalmer4 said, you would also get 85. so i'm guessing you missed a step :)

Answer 32

Both approaches get the right answer, of course. If you were planning a fundraiser, you'd probably do my approach to figure out how many boxes you had to sell (what? we have to sell 160 boxes of fruit door to door in this neighborhood? who are you kidding?) but for tracking how you are doing either is fine.

Answer 33

1 1/8 = 9/8 = 1.125 = 1.13
each box get them 1.13
75 x 1.13 = 84.75 (this is what they have already made)
180 - 84.75 = 95.25 (this is what they need)
1/1.13 = x/95.25 (1 box to 1.13 = x boxes to 95.25)cross multiply
(1.13)(x) = (1)(95.25)
1.13x = 95.25
x = 95.25/1.13
x = 84.29 (I am rounding up) = 85

check...
85 x 1.13 = 96.05
It wouldn't work for 84 because that would = 94.92 (not enough)

Answer 34

If you're going to do arithmetic like this, there's no reason to round off numbers in the middle. 75*1.125 = 84.375
180-84.375 = 95.625
1.125x = 95.625
x = 95.625/1.125
x = 85

Answer 35

that is easier then rounding .

Answer 36

@whpalmer4 I was actually just thinking about that after I was done. :P rounding was not really helping at all.
