A school snack bar sells a mix of granola and raisins. The mix includes 2 pounds of granola for every 3 pounds of raisins. How m
kifflom [539]
The easiest way to solve a problem like this is to cross multiply and solve 

The problem gives us a ratio 
2 pounds of granola = 3 pounds of raisins 
which makes a ratio of \frac{2}{3}
The other ratio is 
? pounds of granola = 24 pounds of raisins
which makes a ratio of \frac{x}{24}

To solve, set them equal to each other ...
\frac{2}{3} =  \frac{x}{24}

Now we must cross multiply...
To cross multiply, we multiply 2 and 24 
and we multiply 3 and x 
Now we have an equation to solve!
3x = 48 
To solve and get your final answer, divide...
x = \frac{48}{3}

x = 16
You'll need 16 pounds of granola

Salinity is a measure of the salt content of a body of water. One researcher measures the salinity of the Indian Ocean as 3.2%.
frosja888 [35]
Divide each percentage to find a multiplier:

34/3.2 = 10.625

The Dead Sea is 10.625 times saltier than the Indian Ocean.

So if Indian Ocean bucket = 56 grams of salt

Multiply that by our multiplier.

56 * 10.625 = 595 grams

The answer is 595 grams
