I'm thirteen years old.

I'm Ok, thanks. How about you?

He told me to go to the zoo.

How do you go to school?

Our house isn't near the school.

Tick cho mk và theo dõi mk nha.

Ta có: 1,5 tạ = 150 kg

Mà ta lại biết: P = 10m

Áp dụng vào công thức trên ta có:

P=10m = 10. 150= 1500 (N)

\(\dfrac{2}{4}\): (\(\dfrac{2}{3}\):\(\dfrac{3}{5}\)) = \(\dfrac{2}{4}\): (\(\dfrac{2}{3}\). \(\dfrac{5}{3}\))

=\(\dfrac{2}{4}\): \(\dfrac{10}{9}\)

= \(\dfrac{2}{4}\). \(\dfrac{9}{10}\)

= \(\dfrac{9}{20}\)

\(\dfrac{3}{4}\):(\(\dfrac{2}{3}\):\(\dfrac{3}{5}\)) = \(\dfrac{3}{4}\): (\(\dfrac{2}{3}\). \(\dfrac{5}{3}\))

= \(\dfrac{3}{4}\): \(\dfrac{10}{9}\)

= \(\dfrac{3}{4}\). \(\dfrac{9}{10}\)

= \(\dfrac{27}{40}\)

Chúc bn học tốt nha!!!

Tick cho mk và theo dõi mk nhé!!!

(\(\dfrac{3}{4}\):\(\dfrac{2}{3}\)) : \(\dfrac{3}{5}\) = (\(\dfrac{3}{4}\). \(\dfrac{3}{2}\)):\(\dfrac{3}{5}\)

= \(\dfrac{9}{8}\):\(\dfrac{3}{5}\)

= \(\dfrac{9}{8}\).\(\dfrac{5}{3}\)

= \(\dfrac{40}{24}\)

=\(\dfrac{20}{12}\)

Tick cho mk và theo dõi mk nha.

Chúc bn học tốt!!!

\(\dfrac{4}{7}\)+\(\dfrac{5}{9}\): x = \(\dfrac{1}{5}\)

\(\dfrac{5}{9}\):x = \(\dfrac{1}{5}\)- \(\dfrac{4}{7}\)

\(\dfrac{5}{9}\): x = \(\dfrac{-13}{35}\)

x= \(\dfrac{5}{9}\):( \(\dfrac{-13}{35}\))

x = \(\dfrac{-175}{117}\)

Vậy x = \(\dfrac{-175}{117}\)

Nhớ tick cho mk nha và theo dõi mk nha!

Chúc bn học tốt!!!
