$3\dfrac{1}{7}+2\dfrac{1}{2}=3\dfrac{1\cdot2}{7\cdot2}+2\dfrac{1\cdot7}{2\cdot7}=3\dfrac{2}{14}+2\dfrac{7}{14}=(3+2)+\dfrac{2+7}{14}=\boxed{5\frac{9}{14}}$

The difference between the two polynomials is 11x²3y³ - 4xy².

<h3>What is the Difference between the Polynomials?</h3>

The difference between two polynomials is the result you get by subtracting one from the other.

Thus:

= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)

= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y

= 11x²3y³ - 4xy²

$\frac{ \frac{8}{5} + ( - \frac{5}{6}) }{ \frac{1}{6} } \\ = \frac{ \frac{8}{5} - \frac{5}{6} }{ \frac{1}{6} } \\ = \frac{ \frac{48- 25}{30} }{ \frac{1}{6} } \\ = \frac{ \frac{23}{30} }{ \frac{1}{6} } \\ = \frac{23}{30} \times 6 \\ = \frac{23}{5}$
