Ai giúp mk giải câu này với 

 

Answer 1

\(\left(30:\frac{7}{2}+0,5\times3-1,5\right)\times\left(\frac{9}{2}-\frac{9}{2}\right):\left(4,5\times100\right)\)

\(=\left(30:\frac{7}{2}+0,5\times3-1,5\right)\times0:\left(4,5\times100\right)\)

\(=0\)

cảm ơn phạm tuấn đạt nhé

Answer 3

( 30 : 7/2 + 0,5 × 3 - 1,5 ) × (9/2 -9/2): (4,5 ×100)

=(30:7/2+0,5×3-1,5)×0:(4,5×100)

=0:(4,5×100)

=0
