\(1\dfrac{13}{15}.0,75-\left(\dfrac{11}{20}+25\%\right):1\dfrac{2}{5}\)
\(=\dfrac{28}{15}.\dfrac{3}{4}-\left(\dfrac{11}{20}+\dfrac{1}{4}\right):\dfrac{7}{5}\)
\(=\dfrac{7}{5}-\left(\dfrac{11}{20}+\dfrac{5}{20}\right):\dfrac{7}{5}\)
\(=\dfrac{7}{5}-\dfrac{16}{20}:\dfrac{7}{5}=\dfrac{7}{5}-\dfrac{4}{5}.\dfrac{5}{7}=\dfrac{7}{5}-\dfrac{4}{7}=\dfrac{49}{35}-\dfrac{20}{35}=\dfrac{29}{35}\)
Tìm thương của B và nghịch đảo của B biết:
B= 1/13/15. 0,75 - ( 11/20+25%): 2/5 là
A.-3/5 B.16/25 C.-9/25 D. 9/25
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 🥺
1 13/15 . 0,75 - (11/20 + 25/100) : 7/5
\(1\dfrac{13}{15}.0,75-\left[\dfrac{11}{20}+25\%\right]:\dfrac{7}{5}\)
1 13/15 . 0,75 - ( 11/20 + 25%) : 7/3
1, A= \(\dfrac{-3}{4}.\left(0,125-1\dfrac{1}{2}\right):\dfrac{33}{16}-25\%\)
2, B= \(1\dfrac{13}{15}.0,75-\left(\dfrac{11}{20}+25\%\right):\dfrac{7}{3}\)
3, C= \(\dfrac{5}{16}:0,125-\left(2\dfrac{1}{4}-0,6\right).\dfrac{10}{11}\)
4, D= \(6\dfrac{5}{12}:2\dfrac{5}{4}+11\dfrac{1}{4}.\left(\dfrac{1}{3}-\dfrac{1}{5}\right)\)
\(1\dfrac{13}{15}\) . 0,75 - \((\dfrac{11}{20}\) + 25%) : \(\dfrac{7}{3}\)
Help me!!!! Giúp tớ với ạ🥺👉🏻👈🏻
\(1\frac{13}{15}\) . 0,75 - ( 11/20 +25% ) :3/7
\(1\frac{13}{15}.0,75-\left(\frac{11}{20}+\frac{25}{100}\right):\frac{3}{7}\)
