Question

Simplify the following.

$\left(15-\overline{2+5}\right)+5+20÷6\times 7$

Answer 1

Given: $\left(15-\overline{2+5}\right)+5+20÷6\times 7$

$$\begin{gathered} \left(15-\overline{2+5}\right)+5+20÷6\times 7=\left(15-7\right)+5+20÷6\times 7 \\ =8+5+20÷6\times 7 \\ =8+5+\frac{20}{6}\times 7 \\ =8+5+\frac{10}{3}\times 7 \\ =8+5+\frac{70}{3} \\ =13+\frac{70}{3} \\ =\frac{13\times 3+70}{3} \\ =\frac{39+70}{3} \\ =\frac{109}{3} \end{gathered}$$

Hence, the required answer is $\frac{109}{3}.$
