Write the Inequality
A number b times -16 is greater than 5. 
A number b is a variable... b. 
Times means multiply. 
-16 is what you are multiplying b by. 
Is greater than means the greater than symbol. 
5 is what the past statements are greater than. 
So this is the inequality. 
-16b > 5
Solve the Inequality
You need to isolate b. 
To do this, divide each side by -16. You do this because b is being multiplied by -16. You know that any number divided by that number equals 1, canceling the number. 
-16b ÷ -16 = b
5 ÷ -16 = -5/16
So you get b > -5/16
So to make the inequality true, b must be more than -5/16. 
Or as an inequality...
b > -5/16
