Herky found that 8 out of every 100 beans in his garden were nibbled by rabbits. How many beans can he expect to be damaged if t

jek_recluse [69]

Answer: 36 beans

Step-by-step explanation:

Make a proportion

For every 100 beans, 8 are damaged

8/100

For every 450 brand, x are damaged

x/450

Set the expressions equal to each other

8/100=x/450

100x=3600

Divide by 100 on both sides

x=36

So, out of 450 beans, 36 should be damaged

Hope this helped! :)
