Length of 1 = 300 = 3 *10^2 nanometers
= 3*10^2/1*10^9 m
= 3*10^(2-9)
= 3*10^-7m
10/6 = 1 2/3
This is because 5 + 5 =10/6
Divide 19 by six.
This gives you 1 2/3
Well when ever you're doing order of operations you always use please excuse my dear aunt sally please means parentheses ALWAYS GO FIRST Excuse means experience which if there's no parentheses exponents go first to my name is multiplication after parentheses multiplication always go first if there's no parentheses dear means division after multiplication comes division on means addition but pretty much after the multiplication parentheses and the division you complete the rest of the problem using the left to right method now the answer to this problem is
The answer is 
.
Let's solve your equation step-by-step.
2b+3b=3
Step 1: Simplify both sides of the equation.
2b+3b=3
(2b+3b)=3(Combine Like Terms)
5b=3
5b=3
Step 2: Divide both sides by 5.
5b/5=3/5
So, the answer is .
325 three hundred twenty-five
