Question

mọi người ơi giúp mik với mình cần gấp : 5/7 +Y x 1/2 = 8/7 :3/2

Answer 1

\(\frac{5}{7}+y\times\frac{1}{2}=\frac{8}{7}:\frac{3}{2}\)

=> \(\frac{5}{7}+y\times\frac{1}{2}=\frac{8}{7}\times\frac{2}{3}\)

=> \(\frac{5}{7}+y\times\frac{1}{2}=\frac{16}{21}\)

=> \(y\times\frac{1}{2}=\frac{16}{21}-\frac{5}{7}=\frac{1}{21}\)

=> \(y=\frac{1}{21}:\frac{1}{2}=\frac{1}{21}\cdot2=\frac{2}{21}\)

Answer 2

5/7 + Y x 1/2 = 8/7 : 3/2

=> 5/7 + Y x 1/2 = 16/21

=> Y x 1/2 = 16/21 - 5/7

=> Y x 1/2 = 1/21

=> Y = 1/21 : 1/2 

=> Y = 2/21

Hok tốt ^^

Answer 3

5/7 +Y x 1/2 = 8/7 :3/2 5/7 +Y x 1/2 = 8/7 x2/3 5/7 +Y x 1/2 = 16/21 5/7 +Y = 16/21 ÷ 1/2 5/7 +Y = 16/21×2/1 5/7 +Y = 32/21 Y=32/21-5/7 Y=32/21-15/21 Y=17/21 Chúc bạn học tốt♡♡

Answer 5

\(\frac{5}{7}+y\times\frac{1}{2}=\frac{8}{7}:\frac{3}{2}\)

\(\frac{5}{7}+y\times\frac{1}{2}=\frac{16}{21}\)

\(y\times\frac{1}{2}=\frac{16}{21}-\frac{5}{7}\)

\(y\times\frac{1}{2}=\frac{1}{21}\)

\(y=\frac{1}{21}:\frac{1}{2}\)

\(y=\frac{2}{21}\)
