Question

\(\frac{4}{7}\)+x=\(\frac{7}{8}\)-\(\frac{1}{4}\)

 

Answer 1

<=>4/7+x=5/8

<=>x=3/56

Answer 2

\(\frac{4}{7}+x=\frac{7}{8}-\frac{1}{4}\)

\(\frac{4}{7}+x=\frac{5}{8}\)

\(x=\frac{5}{8}-\frac{4}{7}\)

\(x=\frac{3}{56}\)

Answer 3

<=> 4/7 + x = 7/8 - 2/8

<=> 4/7 + x = 5/8

<=> x = 5/8 - 4/7

=> x = 3/56

Vậy x = 3/56

Answer 4

3/56

nha

Answer 5

số cần tìm là : 

4/7 + x = 7/8 - 1/4 

4/7 + x = 5/8

         x = 5/8 - 4/7

         x = 35/56 - 32/56

         x = 3/56

đáp số : x= 3/56 

Answer 6

\(\frac{4}{7}+x=\frac{7}{8}-\frac{1}{4}\)

\(\frac{4}{7}+x=\frac{5}{8}\)

\(x=\frac{5}{8}-\frac{4}{7}\)

\(x=\frac{3}{56}\)

Answer 7

\(\frac{4}{7}+x=\frac{7}{8}-\frac{1}{4}\)

\(\frac{4}{7}+x=\frac{7}{8}-\frac{2}{8}\)

\(\frac{4}{7}+x=\frac{5}{8}\)

         \(x=\frac{5}{8}-\frac{4}{7}\)

         \(x=\frac{35}{56}-\frac{32}{56}\)

         \(x=\frac{3}{56}\)

Answer 8

\(\frac{4}{7}+x=\frac{7}{8}-\frac{1}{4}\)

\(\frac{4}{7}+x=\frac{5}{8}\)

\(x=\frac{5}{8}-\frac{4}{7}\)

\(x=\frac{3}{56}\)

Answer 9

4 / 7 +x = 7 / 8 - 1 / 4

4 / 7 +x = 5 / 8 

        x = 5 / 8 - 4 / 7 

       x = 3 / 56

Answer 10

4/7 + x =7/8 -1/4

4/7 + x = 5/8

x          =5/8 -4/7

x          =3/56

Answer 11

Ta có:\(\frac{4}{7}+x=\frac{7}{8}-\frac{1}{4}\Rightarrow\frac{4}{7}+x=\frac{5}{8}\Rightarrow x=\frac{5}{8}-\frac{4}{7}\Rightarrow x=\frac{3}{56}\)

Answer 12

3/56 nha bn

Answer 13

4/7+X=7/8-1/4

4/7+X=5/8

       X=5/8-4/7

       X=3/56
