Answer:
a:b = 2
Step-by-step explanation:
Here we need to operate with terms in order to arrive to a ratio a:b (or a/b).
We have:
 2a−b/6 = b/3
Lets sum b/6 in both sides:
 2a−b/6 + b/6 = b/3 + b/6
 2a = b/3 + b/6
Now, we can multiply and divide b/3 by 2 to make a 6 appear on the denominator and sum it with b/6, this is, use common denominator:
2a = b/3*(2/2) + b/6
2a = 2b/6 + b/6
2a = 3b/6
2a = b/2, as 3/6 = 1/2
Now lets divide both sides by b to make an a/b appear:
2a/b = (b/2)/b
2a/b = 1/2
Finally, multiply both sides by (1/2) or divide by 2:
(2a/b)/2 = 2
a/b = 2
This is, a is twice as b. If b is 1 so a is 2; if b is 45 so a is 90, and so on.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Step one: because fractions are out of 100% you do
 5%+100%= 105
 105 divide by 100 which is equal to 1.05
Step two: it’s says two year so what you do is times the amount by the number you got

.6 divided by 10 is .06 so .6 is 10 times more than .06. Hope this helps!
