Ok, to solve this first you have to set up your proportion:

9/150=x/230

/ is a fraction

x= the number of vials it will take to treat 230 patients

in order to solve this, you have to cross multiply:

9 x 230= 2070

150 · x= 150x

so you get 150x=2070

then divide 2070 by 150

2070/150= 13.8

so it would take 13.8 vials of medicine to treat 230 patients

<span>Okay, firstly, you want to work out how many people will 1 vial of malaria treat. So, you do this: 

150 divided by 9= </span><span>16.6

</span><span>That means for every 1 vial, 16.6 people are treated.
</span>
<span>Since the question asks you to find out how many vials are needed if you're required to treat 230 people, you would do this:
</span>
230 divided by 16.6= <span>13.8

</span>That means you need 13.8 vials to treat 230 people.
