Answer:

The numbers are 38 and 57

Step-by-step explanation:

Let

x-----> the missing smaller number

y----> the missing larger number

we know that

[tex]45=\frac{40+38+46+51+x+y}{6} \\ \\270=175+x+y[/tex]

[tex]x+y= 95[/tex] -----> equation A

[tex]\frac{x}{y}=\frac{2}{3}[/tex]

[tex]x=\frac{2}{3}y[/tex] -----> equation B

substitute equation B in equation A and solve for y

[tex]\frac{2}{3}y+y= 95[/tex]

[tex]\frac{5}{3}y= 95[/tex]

[tex]y=95*3/5=57[/tex]

Find the value of x

[tex]x=\frac{2}{3}(57)=38[/tex]
