If 2a−b/6 = b/3, then ratio a:b = 3 : 2
<h3><u>Solution:</u></h3>Given that 2a−b/6 = b/3
We have to find the ratio of a:b
In mathematics, a ratio indicates how many times one number contains another
A ratio between two or more quantities is a way of measuring their sizes compared to each other
let us first solve the given expression
On cross multiplication we get,
6a - 3b = 6b
6a = 6b + 3b
6a = 9b
To convert a fraction to a ratio, first write down the numerator, or top number. Second, write a colon. Thirdly, write down the denominator, or bottom number
Therefore ratio a:b = 3 : 2
