Question

( 14 và 1/2+ 10 và 4/5 ) x 2=

Answer 1

= (29/2 + 54/5) x 2

= 37/10 x 2

= 74/10

Answer 2

`(14 1/2 + 10 4/5) xx 2`

`= 29/2 xx 2+ 54/5 xx 2`

`= 29 + 108/5`

`= 29 + 21,6`

`= 50,6`

Answer 3

\(\left(14\dfrac{1}{2}+10\dfrac{4}{5}\right)\)x\(2\)

\(=\left(\dfrac{29}{2}+\dfrac{54}{5}\right)\)x\(2\)

\(=\dfrac{253}{10}\)x\(2\)

\(=\dfrac{253}{5}\)
