Question

\(\frac{7}{10}\)-  y = 0,5+ 0,18

Answer 1

)  10/ 7 − y · 4 3 = 5 1

y · 4 3 = 10 7 − 5 1

y · 4 3 = 2 1 y = 2 1 : 4 3

y = 2 1 · 3 4

y = 3 2

Answer 2

\(\frac{7}{10}-y=0,5+0,18\)

\(\frac{7}{10}-y=0,68\)

\(y=\frac{7}{10}-\frac{17}{25}\)

\(y=\frac{1}{50}\)

vậy \(y=\frac{1}{50}\)

Answer 3

=>\(\frac{7}{10}-y=\frac{1}{2}+\frac{9}{50}\)

=> \(\frac{7}{10}-y=\frac{25}{50}+\frac{9}{50}\)

=> \(\frac{7}{10}-y=\frac{34}{50}\)

=> \(y=\frac{7}{10}-\frac{34}{50}\)

=> \(y=\frac{35}{50}-\frac{34}{50}\)

=> \(y=\frac{1}{50}\)
