a,\(\dfrac{3}{2}.\dfrac{4}{5}-x=\dfrac{2}{3}\)
\(\dfrac{4}{5}-x=\dfrac{2}{3}:\dfrac{3}{2}\)
\(\dfrac{4}{5}-x=\dfrac{4}{9}\)
\(x=\dfrac{4}{5}-\dfrac{4}{9}\)
\(x=\dfrac{16}{45}\)

ta có sơ đồ :
st1 : |-----|-----|-----|-----|-----|
st2 : |-----|-----|-----| tổng 336
st3 : |-----|-----|-----|-----|-----|-----|-----|-----|
tổng số phần bằng nhau là :
5+3+8=16 (phần)
số thứ nhất là :
336 : 16 x 5 = 105
số thứ 2 là :
336 : 16 x 3 = 63
số thứ 3 là :
336-(105+63)=168
Đáp số: 168
\(\dfrac{130050}{425}=306\)
\(\dfrac{1}{50}-\dfrac{1}{50.49}-\dfrac{1}{49.48}-....-\dfrac{1}{2.1}\)
=\(\dfrac{1}{50}-\left(\dfrac{1}{1.2}+\dfrac{1}{2.3}+....+\dfrac{1}{49}-\dfrac{1}{50}\right)\)
=\(\dfrac{1}{50}-\left(1-\dfrac{1}{2}+\dfrac{1}{2}-\dfrac{1}{3}+....+\dfrac{1}{49}-\dfrac{1}{50}\right)\)
=\(\dfrac{1}{50}-\left(1-\dfrac{1}{50}\right)\)
=\(\dfrac{1}{50}-\dfrac{49}{50}\)
=\(\dfrac{-24}{25}\)
Dear Mom and Dad,
Greetings from the enchanting city of Prague! The weather here is simply lovely, with clear skies and a gentle breeze. I've spent my days wandering through charming cobblestone streets, exploring majestic castles, and indulging in delicious pastries at local cafes. Tomorrow, I'm planning to take a boat ride along the Vltava River and visit the renowned Charles Bridge. Sending you all my love and wishing you were here to share this incredible experience with me.
Take care,
Linda
