ANSWER
EXPLANATION
To complete the table, we have to see what is the ratio between the given pairs,
[tex]\frac{b}{a}=\frac{15}{3}=\frac{50}{10}=\frac{30}{6}=5[/tex]
This means that b is 5 times a, so the value of b when a = 1 is 5. And, the value of a when b = 80 is 16,
If the pairs of numbers are equivalent ratios, it means that the division between the numbers, for example, b/a, is constant - i.e. it always gives the same result. In this case, the ratio is always 5.
