I keep tying but i cant get the answer. Please help
Scrat [10]
B is the correct answer. To find out why it is, we can simply put 2,800, the whole, as 100% and 6.2 into x=6.2. The left sides of both of them have the same units, and both right sides have the same units, so we can do something such as 2800/x=100%/6.2%. Then, you simply solve for x.
 
STEPS:
2800/x=100/6.2
<span>(2800/x)*x=(100/6.2)*x       - </span>we multiply both sides of the equation by x
<span>2800=16.129032258065*x       - </span>we divide both sides of the equation by (16.129032258065) to get x
<span>2800/16.129032258065=x </span>
<span>173.6=x </span>
<span>x=173.6</span>
