Question

How do I simplify HUGE Fractions without Calculator? Please Explain how with detail!!!

1) 800000/3200000

2) 7846837/33628738

Answer 1

you can "cancel" equal number of trailing zeros from the top and bottom, for starters

Answer 2

take off the zeroes
for the first one
so u would get 8/32
simplify that even farther and u get 1/4

Answer 3

for the bottom one, I would round to 8,000,000/34,000,000
cancel zeros
8/34
divide by 2
4/17
or even more roughly, 4/16 = 1/4

Answer 4

do they want it exactly?

Answer 5

So we have to remove the zeroes till they are equal in both numbers?
Example:
100[00000000] & 1[00000000]
which will make:
100 & 1
????????

Answer 6

which i doubt but u never know i suppose

Answer 7

and yea that works take off zeros of equal amounts from the top and bottom and from there simplify it

Answer 8

Is THIS:
7846837/33628738
Possible without calculator?

Answer 9

yes. 100/10 is the same as 10
or 1000/100 is 10
you are dividing top and bottom by 10 each time you cancel a 0

Answer 10

depends
do u have to round or get an exact answer?

Answer 11

Actually the real question was:
800000/3200000

But i wrote this:
7846837/33628738

myself to see how to solve it without that "trailing zero" process

Answer 12

why.....

Answer 13

eh the 2nd one would take forever to solve if you had to solve as is

Answer 14

Cause I have an Exam today and Im "sheit" in Maths. Don't even know how to simplify Fractions... And the Exam is without Calculator

Answer 15

Oh OK then, that means they would not give that kinda Question in exam which has Calculator Prohibited
right?

Answer 16

just find a number that they can both b divided by in most cases 2 is easier but takes longer

Answer 17

notice that
7846837/33628738 =0.23333724268
and the rounded estimate
4/17 = 0.235

Answer 18

pretty much what he said

Answer 19

WITHOUT CALCULATOR IS THE SECOND ONE POSSIBLE? I MEAN WOULD THEY GIVE IN EXAM WHICH DOESN'T HAVE CALCULATOR INVOLVED?

Answer 20

easier ways and yes
if you know simple arithmatics

Answer 21

THE FIRST I UNDERSTAND

Answer 22

if you have time, memorize some of the divisibility rules

Answer 23

WITHOUT CALCULATOR IS THE SECOND ONE POSSIBLE? I MEAN WOULD THEY GIVE IN EXAM WHICH DOESN'T HAVE CALCULATOR INVOLVED?
only if you are testing to be "rain man"

Answer 24

Wut?

Answer 26

lol just do this if they actually do give you something like that take one of the numbers find a number you can divide into that number evenly and see if it goes the same with the others and just keep on doing this
