Question

5/12 + 8/3 : (-4)² - 30%

Answer 1

`= 5/12 + 8/(3xx16) - 3/10`

`= 5/12 + 1/6 - 3/10`

`= (25 + 10 - 18)/60`

`= 17/60`.

Answer 2

\(\dfrac{5}{12}+\dfrac{8}{3}\div\left(-4\right)^2-30\%\)

\(\Rightarrow\dfrac{5}{12}+\dfrac{8}{3}\div\left(-4\right)^2-\dfrac{3}{10}\)

\(\Rightarrow\dfrac{5}{12}+\dfrac{8}{3}\div-16-\dfrac{3}{10}\)

\(\Rightarrow\dfrac{5}{12}+-\dfrac{1}{6}+\dfrac{3}{10}\)

\(\Rightarrow\dfrac{1}{4}+\dfrac{3}{10}\)

\(\Rightarrow\dfrac{11}{20}\)
