a) \(x:\frac{2}{3}=150\)
\(x=150.\frac{2}{3}\)
\(x=100\)
b) \(\frac{35}{9}:x=\frac{35}{6}\)
\(x=\frac{35}{9}.\frac{6}{35}=\frac{2}{3}\)
c,d tương tự
a ) x : 2/3 = 150 c ) x : 4/7 = 180
x = 150 x 2/3 x = 180 x 4/7
x = 100 x = 720/7
b ) 35/9 : x = 35/6 d ) 49/8 : x = 49/5
x = 35/9 : 35/6 x = 49/8 : 49/5
x = 2/3 x = 5/8
a) x : \(\frac{2}{3}\)= 150
x = 150 x \(\frac{2}{3}\)
x = 100
b) \(\frac{35}{9}:x=\frac{35}{6}\)
x = \(\frac{35}{9}\): \(\frac{35}{6}\)
x = \(\frac{2}{3}\)
c) x : 4/7 = 180
x = 180 x 4/7
x = 720/7
d) 49/8 : x = 49/5
x = 49/8 : 49/5
x = 5/8
nhớ k cho mik nha mik đang rất cần cái k của bn
a) x : 2/3 = 150
x = 150 x 2/3
x = 100
b) 35/9 : x = 35/6
x = 35/9 : 35/6
x = 2/3
c) x : 4/7 = 180
x = 180 x 4/7
x = 720/7
d) 49/8 : x = 49/5
x = 49/8 : 49/5
x = 5/8
