Question

\(\dfrac{9}{48}x\left(-2.4\right)+\left(\dfrac{1}{4}+\dfrac{13}{20}\right):2\)

Answer 1

\(=\dfrac{-9}{20}+\dfrac{9}{10}:2\)

\(=-\dfrac{9}{20}+\dfrac{9}{20}\)

\(=0\)

Answer 2

\(=\dfrac{9}{48}\times\left(-8\right)+\dfrac{9}{20}\times\dfrac{1}{2}=-\dfrac{3}{2}+\dfrac{9}{40}=-\dfrac{60}{40}+\dfrac{9}{40}=-\dfrac{51}{40}\)

Answer 3

9/48 x (- 2,4) + 9/10 : 2

= -9/20 + 9/20

= 0
