\(\dfrac{2024\times2024-1010}{2023\times2024+1014}\)

\(=\dfrac{2024\times\left(2023+1\right)-1010}{2023\times2024+1014}\)

\(=\dfrac{2024\times2023+1014}{2023\times2024+1014}\)

Bạn cần hỏi điều gì?

what

\(\dfrac{73}{24}-\dfrac{22}{6}:\dfrac{11}{8}=\dfrac{73}{24}-\dfrac{11}{3}\times\dfrac{8}{11}\)

\(=\dfrac{73}{24}-\dfrac{8}{3}=\dfrac{73}{24}-\dfrac{64}{24}=\dfrac{9}{24}=\dfrac{3}{8}\)

bang:1200000

1000x30:2x80

=30000:2x80

=15000x80

=1200000

Phân số lớn là \(\left(\dfrac{13}{12}+\dfrac{1}{4}\right):2=\left(\dfrac{13}{12}+\dfrac{3}{12}\right):2=\dfrac{16}{12}:2=\dfrac{16}{24}=\dfrac{2}{3}\)

Phân số bé là \(\dfrac{2}{3}-\dfrac{1}{4}=\dfrac{8}{12}-\dfrac{3}{12}=\dfrac{5}{12}\)

Cần gấp lắm ạaaaaa 🥹💞🍫

1 tạ 28kg=128kg

1 yến=10kg

Khối lượng măng khô bác Hưng thu về là:

128:16x10=8x10=80(kg)

Chiều dài hình chữ nhật là \(\dfrac{8}{5}:\dfrac{5}{7}=\dfrac{8}{5}\times\dfrac{7}{5}=\dfrac{56}{25}\left(m\right)\)

\(2460+300\times\left\{96:8+15\right\}\)

\(=2460+300\times\left\{12+15\right\}\)

\(=2460+300\times27\)

\(=2460+8100\)

\(=10560\)

2460+300.(96:8+15)

=2460+300.(12+15)

=2460+300.27

=2460+8100=10560

\(\dfrac{1}{2}+\dfrac{1}{6}+...+\dfrac{1}{90}\)

\(=\dfrac{1}{1\times2}+\dfrac{1}{2\times3}+...+\dfrac{1}{9\times10}\)

\(=1-\dfrac{1}{2}+\dfrac{1}{2}-\dfrac{1}{3}+...+\dfrac{1}{9}-\dfrac{1}{10}\)

\(=1-\dfrac{1}{10}=\dfrac{9}{10}\)
