Question

(3/2 + 9/8) * 2

Answer 1

\(=\left(\dfrac{3.4+9}{8}\right)\times2=\dfrac{21}{8}\times2=\dfrac{21}{4}\)

Answer 2

\(\left(\dfrac{3}{2}+\dfrac{9}{8}\right) . 2=\left(\dfrac{12}{8}+\dfrac{9}{8}\right) . 2=\dfrac{21}{8} . 2=\dfrac{21 . 2}{8}=\dfrac{21}{4}\)

Answer 3

\(\dfrac{3}{2}\) + \(\dfrac{9}{8}\) x \(2\) = \(\dfrac{12}{8}\) + \(\dfrac{9}{8}\) = \(\dfrac{21}{8}\) x \(2\) = \(\dfrac{21}{4}\)

Answer 4

( \(\dfrac{3}{2}\) + \(\dfrac{9}{8}\) ) x 2

=     \(\dfrac{21}{8}\)    x 2

=            \(\dfrac{21}{4}\)
