Respuesta :
[tex]\bf 2a=9b\implies \stackrel{\textit{cross-multiplying}}{\cfrac{a}{b}=\cfrac{9}{2}}\qquad \qquad a:b\implies 9:2[/tex]
Answer:
The answer is a:b is 9:2.
Step-by-step explanation:
In order to determine the answer, we have to know about ratio.
A ratio is a fraction of two measures. If a fraction is a/b, we can express this fraction as a:b, so:
a/b=a:b
In this case, we have an expression that shows the variable "a" and "b". So we have to modify this expression to get the correct form of a ratio.
[tex]2a=9b\\\frac{a}{b}=\frac{9}{2}[/tex]
Then, we express the fraction as:
a:b=9:2
Finally, the ratio for a:b is 9:2.
