<h3>What are the ratio and proportion?</h3>
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
For example 3/8 here 3 is the numerator and 8 is the denominator the value of the fraction will be less than 1 or greater than it depends upon the numerator and denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
$9.75 ⇔ 65 text massages
Divide by 9.75
$1 ⇔ 6.67 massages,

$6.60 ⇔ 44 text messages.
Hence "If we use $6.60 then 44 massages will go to be sent".
