\(1\frac{13}{15}\) . 0,75 - ( 11/20 +25% ) :3/7
=\(\frac{28}{15}\) . 3/4 - ( 11/20 +25/100 ) :3/7
=28/15. 3/4- 4/5 : 3/7
=7/5 - 28/15
=-7/15
Thấy đúng thì bấm đúng cho mh nha!!!
\(1\frac{13}{15}.0,75-\left(\frac{11}{20}+\frac{25}{100}\right):\frac{3}{7}\)
1 13/15 . 0,75 - ( 11/20 + 25%) : 7/3
1 13/15 . 0,75 - (11/20 + 25/100) : 7/5
Thực hiện phép tính:
A=\(\left(\frac{3}{8}+\frac{-3}{4}+\frac{7}{12}\right):\frac{5}{6}+\frac{1}{2}\)
B=1\(\frac{13}{15}.0,75-\left(\frac{11}{20}+25\%\right):\frac{7}{5}\)
\(1\dfrac{13}{15}.0,75-\left[\dfrac{11}{20}+25\%\right]:\dfrac{7}{5}\)
\(1\dfrac{13}{15}\) . 0,75 - \((\dfrac{11}{20}\) + 25%) : \(\dfrac{7}{3}\)
Help me!!!! Giúp tớ với ạ🥺👉🏻👈🏻
A,. 1 13/15 .0,75 -(11/20+25%):7/5
B, (2/3)^2:(-8)-(-1/4+9/20):1 4/5
Giúp em với ạ 🥺
