1/5 * 7/8 * 1/6

OpenStudy (ddos_dragon):

.20 * 0.875 * 0.166 (Repeating)

OpenStudy (ddos_dragon):

Once converted, it becomes A LOT easier.

alones (alones):

i thought you ust could multiply it in fraction form which i got 7/240

OpenStudy (ddos_dragon):

You could, I just find it to be easier to multiply decimals.

OpenStudy (anonymous):

i agree @Ddos_Dragon

alones (alones):

okayii :) i get you now

OpenStudy (anonymous):

0.02905?

OpenStudy (ddos_dragon):

I agree.

OpenStudy (anonymous):

So whats the answerr?

OpenStudy (ddos_dragon):

So you want it in fraction form?

OpenStudy (anonymous):

Yes please?

OpenStudy (anonymous):

Since the answer choices are in fraction form..

OpenStudy (ddos_dragon):

0.02905/100000 "Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)"

OpenStudy (ddos_dragon):

Now, to simplify this we need to ask ourselves if the numerator and the denominator can be divided by the same number.

OpenStudy (ddos_dragon):

Can it? (Sorry not aloud to give direct answers. This makes the whole process rather slow.)

OpenStudy (ddos_dragon):

May I see the multiple choice list?

OpenStudy (anonymous):

Well the answer to 0.02905 * 10,000 was 290.5

OpenStudy (anonymous):

So I really dunno

OpenStudy (anonymous):

Answer yes u can

OpenStudy (anonymous):

A. 7/8

OpenStudy (anonymous):

B. 13/19

OpenStudy (anonymous):

C. 1/2

OpenStudy (anonymous):

D. 7/48

OpenStudy (anonymous):

Thats the list

OpenStudy (ddos_dragon):

02905/100000 is our fraction. Now we need to find a number that can divide into both the numerator and the denominator.

OpenStudy (anonymous):

Mhm lemme check

OpenStudy (anonymous):

7/8?

OpenStudy (anonymous):

7/8 makes it 83/250

OpenStudy (ddos_dragon):

Sorry, am multi - tasking. 7/8 does not bake 83/250

OpenStudy (ddos_dragon):

make*

OpenStudy (anonymous):

WHat about 7/48

OpenStudy (ddos_dragon):

Yes. i actually had just estimated it being 7/48. I would go with that. Use caution.

OpenStudy (ddos_dragon):

I haven't fraction converted in a while.

OpenStudy (ddos_dragon):

*I

OpenStudy (anonymous):

Yeah if I get this wrong I fail xD

OpenStudy (ddos_dragon):

It may be wrong. But that is all the help I can supply you with.

OpenStudy (ddos_dragon):

Well... Crap..

OpenStudy (anonymous):

I'll divide it first to check

OpenStudy (ddos_dragon):

I am sorry, I am not able you supply sufficient help, perhaps @Michele_Laino can.

OpenStudy (anonymous):

= 249/125 = 1 124/125 was the answer I got

OpenStudy (ddos_dragon):

Let us start from scratch and not convert to decimals..

OpenStudy (anonymous):

Btw it was correct

OpenStudy (anonymous):

But I failed the test

OpenStudy (ddos_dragon):

What was?

OpenStudy (ddos_dragon):

Damn..

OpenStudy (anonymous):

Got 2 and 4 wrong

OpenStudy (ddos_dragon):

Sorry to hear that. I apologize for not being of well enough help.
