tích mik nha
mik ko nói dối
a, 2/3 - 2/9 + 7/9 = 6/9 - 2/9 + 7/9 = 10/9
b, 7/6 + 3/5 : 6 = 7/6 + 3/5 x 1/6 = 7/6 + 1/10 = 70/60 + 6/10 = 76/10 = 38/5
c, x : 6/25 = 18
x = 18 x 6/25
x = 36/25
d, ( 2/5 + 4/7) : x = 17/5
29/35 : x = 17/5
x = 29/35 : 17/5
x = 29/119
\(a.\dfrac{2}{3}-\dfrac{2}{9}+\dfrac{7}{9}=\dfrac{6}{9}-\dfrac{2}{9}+\dfrac{7}{9}=\dfrac{4}{9}+\dfrac{7}{9}=\dfrac{11}{9}\\ b.\dfrac{7}{6}+\dfrac{3}{5}:6=\dfrac{7}{6}+\dfrac{3}{5}\times\dfrac{1}{6}=\dfrac{7}{6}+\dfrac{1}{10}=\dfrac{70}{60}+\dfrac{6}{60}=\dfrac{76}{60}=\dfrac{19}{15}\\ c.x:\dfrac{6}{25}=18\\ x=18\times\dfrac{6}{25}\\ x=\dfrac{108}{25}\\ d.\left(\dfrac{2}{5}+\dfrac{4}{7}\right):x=\dfrac{17}{5}\\ \dfrac{34}{35}:x=\dfrac{7}{5}\\ x=\dfrac{34}{35}:\dfrac{7}{5}\\ x=\dfrac{34}{49}\)
a)3/4 x 2/9 + 1/3
=1/6 + 1/3
=1/6 + 2/6
=1/2
b)5/4:2.9+1/2
=1.25 : 2.9 + 1/2
=25/58 + 1/2 =27/29
c)7/2 - 1/4 x 1/5
=7/2 - 1/20
=69/20
d)5/4+1/5:2/3
=5/4 + 3/10
=31/20
Học tốt!
(1-1/2)×(1-1/3)×(1-1/4)×(1-1/5)×1-1/6=1/2×2/3×3/4×4/5×5/6=1/6
B=\(5\dfrac{9}{10}:\dfrac{3}{2}-\left(2\dfrac{1}{3}.4\dfrac{1}{2}-2.2\dfrac{1}{3}\right):\dfrac{7}{4}\)
B=\(\dfrac{59}{10}.\dfrac{2}{3}-\left(\dfrac{7}{3}.\dfrac{9}{2}-2.\dfrac{7}{3}\right):\dfrac{7}{4}\)
B=\(\dfrac{59}{15}-\left(\dfrac{21}{2}-\dfrac{14}{3}\right):\dfrac{7}{4}\)
B=\(\dfrac{59}{15}-\left(\dfrac{63-28}{6}\right):\dfrac{7}{4}\)
B=\(\dfrac{59}{15}-\dfrac{35}{6}:\dfrac{7}{4}\)
B=\(\dfrac{59}{15}-\dfrac{10}{3}=\dfrac{59-50}{15}\)
\(\Rightarrow B=\dfrac{3}{5}\)
