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: ¹/₁₂ watermelon
Step-by-step explanation:
Mrs. Parker had a watermelon which she cut into fourths and then gave one of those pieces to her children.
This means that she gave them 1/4 of a watermelon.
There are 3 children and they are to share this piece equally:
= 1/4 ÷ 3
= 1/4 * 1/3
= 1/12
<em>Each child will get 1/12 of the water melon. </em>
