Question

Express each of the following as a rational number​

Answer 1

Answer:

expressing {$(3/2)^{-1}$ ÷ $(-2/5)^{-1}$ }  as rational number:  -4/15

Step-by-step explanation:

$(3/2)^{-1}$ can be written as 2/3

$(-2/5)^{-1}$ can be written as (-5/2)

so; {$(3/2)^{-1}$ ÷ $(-2/5)^{-1}$ } = (2/3) ÷ (-5/2)

{$(3/2)^{-1}$ ÷ $(-2/5)^{-1}$ }  = -(2*2)/(3*5) = -4/15

expressing {$(3/2)^{-1}$ ÷ $(-2/5)^{-1}$ }  as rational number:  -4/15
