Question

5
2,
find the mean of -7/2 and 5/4​

Answer 1

Step-by-step explanation:

let a=-7/2

b=5/4

mean=(a+b)/2

mean=((-7/2)+(5/4))/2

= -1.125

Answer 2

$The \: mean \: of \: \frac{-7}{2} \:and \: \frac{5}{4}$

$= \Big( \frac{\frac{-7}{2} + \frac{5}{4}}{2}\Big)$

$= \Big( \frac{\frac{-14+5}{4}}{2}\Big)$

$= \Big( \frac{\frac{-9}{4}}{2}\Big)$

$= \frac{-9}{4} \times \frac{1}{2}$

$= \frac{-9}{8}$

Therefore.,

$\red{The \: mean \: of \: \frac{-7}{2} \:and \: \frac{5}{4}}$

$\green {= \frac{-9}{8}}$
