Question

can someone teach me how to turn 8/5 into 13/5 (this is a mixed number)

Answer 1

add 1

Answer 2

Always 1?

Answer 3

just for this specific problem
8/5+x=13/5
x=(13/5)-(8/5)
x=(13-8)/5
x=5/5
x=1

Answer 4

what if I want put 42.2857 into a mixed number. Can you guide me please

Answer 5

do u know how to write .2857 as a fraction?

Answer 6

0.2857 = 2857/10000, right?

Answer 7

422857/10000

Answer 8

yes now first u would write the decimal as afraction like u did then add whatever is in front of it to that decimal so:
42+(2857/10000)

Answer 9

next u want to make it a mix number so u need the 42 to have the same denominator as the fraction u just made.

Answer 10

I dont get where did you get 42 from?

Answer 11

its what's before the decimal point:
42.2857

Answer 12

ahhh got it

Answer 13

continue, please

Answer 14

ok so now u want the 42 and the (2857/10000) to have the same denominator so we rewrite 42 as 42/1 so now its
(42/1)+(2857/10000)
now we multiply the top and bottom of the 42/1 by the denominator in the fraction we first made. the 10000 out of the 2857/10000
so its
(42/1)(10000/10000)+(2857/10000)

Answer 15

ok

Answer 16

when we simplify that it becomes
(420000/10000)+(2857/10000)
now since the have the same denominator we can combine the fraction:
(420000+2857)/(10000)

Answer 17

and simplify:
422857/10000

Answer 18

I think I got it. Gonna try some exercises and if I get stacked I ask you for help again ;)

Answer 19

so thats the mathematical way to do it. if u have a decimal the easy way to do it is count how many numbers are behind the decimal point rewrite it without a decimal point then divide it by 1 and a zero for each number u counted:
42.2857 there's 4 numbers behind the decimal point
so rewrite it without a decimal point:
422857
now divide that number by 1 and a zero for however many numbers are behind the decimal point. since there is 4 we divide by 10000.
if it was 3 the we would divide by 1000. if it was 5 we would divide by 100000 and so on. since its 4 it becomes
422857/10000

Answer 20

sure

Answer 21

I have to solve a problem with this kind of numbers and according to my book 42.2857 = 42 2/7

Answer 22

what ur book wrote is not necessarily tru unless it told u to round off to the nearest hundred thousandth spot

Answer 23

well I got 42 2/7 and I did the following

42*7 + 2 = 296/7 = 42.285714285714285714285714285714

Answer 24

I think I messed thing up, sorry

Answer 25

yes which islightlydifferent from 42.2857 because the 1 u solved keeps goin. what did the problem specifically ask u to do?

Answer 26

sorry for not replaying faster. My dog unplugged the source cable of the computer.

The problem says the following:

I have a debt of $183, after one month I have payed off 42 2/7. What is the amount of money to pay left?

Answer 27

oo then u have to do 183-(42+2/7)
so it becomes:
183-42-2/7
now u can subtract the whole numbers first so it becomes:
141-2/7
so what we would dohereis take 1 from the 141:
140+1
now we can change that to have the same denominator asthe fraction
140+(7/7)
so now we can subtract the 2/7
140+7/7-2/7=
140+(7-2)/7
140+5/7

Answer 28

dollars

Answer 29

Definitively, that is the answer. Thank you sooo much ;)
