Question

The ratio of metal objects to glass objects in a recycling
bin is 2:9.
The glass objects are all either bottles or jars, and the ratio
of glass bottles to glass jars is 4: 5.
There are 20 glass jars in the recycling bin.
Work out how many metal objects are in the recycling bin.

Answer 1

Answer:

8 metal objects

Step-by-step explanation:

Since there are 20 glass jars in the recycling bin and the ratio of glass bottles to jars is 4:5, we know that there are 16 glass bottles since 20/5=4 and 4*4=16.

Moving on, we need to add up all the total glass objects, so 20+16=36 total glass objects.

As we did before, we divide 36/9=4 to find the number of metal objects that can be displayed through 2*4=8 metal objects in the recycling bin.

To check our work, we can simplify 8/36 to 2/9, meaning that our calculations were correct.

So, there are a total of 8 metal objects in the recycling bin.

Hope this helps!
