Question

Look at this information about recycling:

20 large plastic bottles can be recycled to make 1 fleece jacket
How many fleeces can be made with 280 large plastic bottles?

Answer 1

14 fleeces can be made from 280 large plastic bottles.

Explanation:

Given that:

20 large plastic bottles can be recycled to make 1 fleece jacket.

Ratio of bottles to jacket = 20:1

Number of large plastic bottles = 280

Let,

x be the number of fleece jackets.

Ratio of large bottles to fleece jackets = 280 : x

This is a proportional relationship.

20 : 1 :: 280 : x

Product of mean = Product of extreme

280 = 20x

20x = 280

Dividing both sides by 20

`(20x)/(20)=(280)/(20)\\x = 14`

Hence,

14 fleeces can be made from 280 large plastic bottles.
