a bottle of soda had 4 and 2/7 of the daily re commended sugar. if you were to drink 1/2 of the bottle. how much of the daily re
andreyandreev [35.5K]
Well this is easyyy:) you just need to multiply 4 and 2/7 by 1/2
buttt before we set up our question lets get 4 and 2/7 as an improper fraction 
    2
4 ----
    7
we do that by multipying the 4 and 7 and then adding 2 soo lets do that 
4 x 7 = 28 
28 + 2 = 30 
look we have our numerator!! (the top number)
and we dont have to do anything to the numerator just keep it the same as 7 :) lets look at our new improper fraction

  30 
------
   7
see now we can set up our problem:)

  30         1
------ x  -----
<span>   7          2
</span>now all we do is multiply across:)

  30         1  = 30 x 1 = 30 
------ x  -----
<span>   7          2  = 7 x 2 = 14 
</span>here is our new fraction
 
  30
------
  14
wait lets simplify it by dividing each number by 2 

  30   ÷ 2 = 15 
------
<span>  14   </span>÷ 2 = 7 
ahh this is better here is our simpified fraction
  
  15 
-------
   7
or as a decimal it is 2.142857143 
either one is the correct answer:)
if this helped you then
