(1/2 + 0,8 – 4/3 ) . ( 2.3 + 47/25 – 1,28 ) = ( 1/2 + 4/5 – 4/3 ) . ( 2.3 + 47/25 – 32/25 ) = ( 5/10 + 8/10 – 4/3 ) . ( 6/1 + 47/25 – 32/25 ) = (13/10 – 4/3) . ( 197/25 – 32/25 ) = -1/30 . 33/5 = -11/50 Trả lời
($\frac{1}{2}$+0,8-$\frac{4}{3}$)×(2×3+$\frac{47}{25}$-1,28) =$\frac{-1}{30}$ × $\frac{33}{5}$ =$\frac{-11}{50}$ Trả lời
(1/2 + 0,8 – 4/3 ) . ( 2.3 + 47/25 – 1,28 )
= ( 1/2 + 4/5 – 4/3 ) . ( 2.3 + 47/25 – 32/25 )
= ( 5/10 + 8/10 – 4/3 ) . ( 6/1 + 47/25 – 32/25 )
= (13/10 – 4/3) . ( 197/25 – 32/25 )

($\frac{1}{2}$+0,8-$\frac{4}{3}$)×(2×3+$\frac{47}{25}$-1,28)
=$\frac{-1}{30}$ × $\frac{33}{5}$
