3m^2n^3 - 2mn^2 +15mn divided by 3mn​

Answer»

Given \: \frac{3m^{2}n^{3} - 2mn^{2} + 15mn}{<klux>3MN</klux>}

/* DIVIDE each TERM by 3mn , we GET */

= \frac{3m^{2}n^{3}}{3mn} - \frac{2mn^{2}}{3mn} + \frac{15mn}{3mn}

= \frac{3mn \times mn^{2}}{3mn} - \frac{mn \times 2n}{3mn} + \frac{3mn\times 5}{3mn}

= mn^{2} - \frac{2}{3} n + 5

THEREFORE.,

\red {\frac{3m^{2}n^{3} - 2mn^{2} + 15mn}{3mn}}

\green { =mn^{2} - \frac{2}{3} n + 5}
