Question

I need to know what to do

Answer 1

1) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
$\frac{35}{185}$ = $\frac{x}{100}$

Next, you would cross multiply. 
185x = 3,500

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 185. 
x = 18.918%

Your answer was correct!

2) First, you would need to create an equation for this problem. Let x represent the unknown 85%. 
$\frac{x}{190}$ = $\frac{85}{100}$

Next, you would cross multiply. 
100x = 16150

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100. 
x = 161.5

3) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
$\frac{24}{128}$ = $\frac{x}{100}$

Next, you would cross multiply. 
128x = 2,400

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 128. 
x = 18.75%


I hope this helps!
