Question

Find a rational number halfway in between the two numbers,4and15

Answer 1

The final answer is 27/70

For this question, we are simply finding the arithmetic mean between the two rational numbers, that will give us the value of the rational number that is halfway.

`\begin{gathered} =((4)/(7)+(1)/(5))/(2) \\ =((27)/(35))/(2) \\ =(27)/(35)^{}/(2)/(1) \end{gathered}`
`\begin{gathered} =(27)/(35)\text{ }*\text{ }(1)/(2) \\ =(27)/(70) \end{gathered}`

The final answer is

`(27)/(70)`
