Answer 2

Question

$\rm{ \bigg(\dfrac{18}{5} \bigg) + \bigg( - \dfrac{7}{25} \bigg)}$

Solution

$\rm{\bigg(\dfrac{18}{5} \bigg) + \bigg( - \dfrac{7}{25} \bigg)} \\ \\ \\ = \frac{18}{5} -\frac{7}{25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\\\\\\rm{LCM = 25.}\\ \\ \\ = \frac{18 \times 5}{5 \times 5} - \frac{7 \times 1}{25 \times 1} \\ \\ \\ = \frac{90}{25} - \frac{7}{25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ = \frac{90 - 7}{25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\= \underline{\underline\frac{83}{25}=3\dfrac{8}{25}}. \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Therefore,

$\bigstar \: \: \:\boxed{\boxed{\bf{\bigg(\dfrac{18}{5} \bigg) + \bigg( - \dfrac{7}{5} \bigg) = \dfrac{83}{25}}=3\dfrac{8}{25}}}$
