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

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

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

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