Question

If 38% of plastic bottles in a production line are blue and the remaining 7750 plastic bottles are brown, how many plastic bottles are blue? (show all working out)

Please help, xox :)

Answer 1

Hello,

First we will search for 100% (or 1% it's up to you) :

100 - 38 = 62 % are the remaining 7750 bottles.

So :

7750 bottles --> 62 %
x bottles --> 100%

Therefore :


`x= (7750*100)/(62)`

`x= 12 500`

Now we know for 100 %, we just have to look for 38 %.

12500 bottles --> 100 %
x bottles --> 38%

Therefore :


`x = (12500*38)/(100)`

`x = 4750`

So, 4750 plastic bottles are blue.

Hope this helps !

Answer 2

Hello there.

If 38% of plastic bottles in a production line are blue and the remaining 7750 plastic bottles are brown, how many plastic bottles are blue?

Answer: 7750 is 68%
7750/68 = 125
125 is 1%
38 x 125 = 38%
38 x 125 = 4750
There are 4750 blue bottles.
