#(6m^2 - 1)/(15m^3)#

#2/(5m) - 1/(15m^3)#

We need a common denominator:

#(3m^2)/(3m^2) xx (2)/(5m) - (1)/(15m^3)#

#(6m^2)/(15m^3) - (1)/(15m^3)#

#(6m^2 - 1)/(15m^3)#

#(6m^2-1)/(15m^3)#

Expand the fraction

#(3m^2*2)/(3m^2*5m)-1/(15m^3)#

Calculate the products

#(6m^2)/(15m^3)-1/(15m^3)#

Write all the numerators above the common denominator

#(6m^2-1)/(15m^3)#
