Answer:
![5+2*(7-4) =11](https://tex.z-dn.net/?f=5%2B2%2A%287-4%29%20%3D11)
Step-by-step explanation:
This expression was kind of trial and error for me seeing as I'm not really good at logic, but this is pretty basic. There are three possible places the parentheses can be placed (assuming each pair holds 2 terms);
The answer to the first expression would be 45, which is not equal to 11.
The answer to the second expression would be 15, which is also not equal to 11.
The answer to the last expression is 11, so that is the correct answer.
Hope this helped :D

Answer:
The greatest amount of fizzy drink he can make is 420 ml
Step-by-step explanation:
we know that
The ratio of the parts of orange juice to parts of lemonade is
![\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D)
so
using proportion
Find out the milliliters of lemonade needed to make fizzy drink with 300 ml of orange juice
Let
x -----> milliliters of lemonade needed
![\frac{5}{2}=\frac{300}{x}\\\\x=300*2/5\\\\x=120\ ml](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%3D%5Cfrac%7B300%7D%7Bx%7D%5C%5C%5C%5Cx%3D300%2A2%2F5%5C%5C%5C%5Cx%3D120%5C%20ml)
<em>Find the greatest amount of fizzy drink he can make</em>
Adds the milliliters of lemonade plus the milliliters of orange juice
![120+300=420\ ml](https://tex.z-dn.net/?f=120%2B300%3D420%5C%20ml)
therefore
The greatest amount of fizzy drink he can make is 420 ml
