Question

tim  x

\(\frac{25-x}{56}=\frac{6}{16}\)

Answer 1

25 - x / 56 = 6/16

( 25 - x ) : 56 = 6/16

25 - x = 6/16 x 56

25 - x = 21

      x = 25 - 21

      x = 4

Answer 2

\(\frac{25-x}{56}=\frac{6}{16}\)

\(\frac{x}{56}=25-\frac{6}{16}\)

\(\frac{x}{56}=24\frac{5}{8}\)

\(\frac{x}{56}=24\frac{35}{56}\)

\(\frac{x}{56}=\frac{24\cdot56+35}{56}\)

\(\frac{x}{56}=\frac{1379}{56}\)

Vậy số cần tìm là  \(1379\)

Answer 3

25-X= 6x56:16
