Answer 1

The missing value is 21.

The ratio value of the double number line is $\frac{7}{2}$.

Solution:

Ratio of the given number line is

$\frac{7}{2}=\frac{7\div1}{2\div1}=\frac{7}{2}$

$\frac{14}{4}=\frac{14\div2}{4\div2}=\frac{7}{2}$

$\frac{28}{8}=\frac{28\div4}{8\div4}=\frac{7}{2}$

$\frac{35}{10}=\frac{35\div5}{8\div5}=\frac{7}{2}$

Hence the common ratio of the number line is $\frac{7}{2}$.

The missing ratio is

$\frac{7}{2} =\frac{7\times3}{2\times3}= \frac{21}{6}$

Hence the missing value is 21.
