Question

Tìm X (lời giải đầy đủ):

a.9/14 : X = 3/7

b.7/15 x X = 7/10

Answer 1

a.\(\dfrac{9}{14}:x=\dfrac{3}{7}\)

\(x=\dfrac{9}{14}:\dfrac{3}{7}\)

\(x=\dfrac{3}{2}\)

b.\(\dfrac{7}{15}\times x=\dfrac{7}{10}\)

\(x=\dfrac{7}{10}:\dfrac{7}{15}\)

\(x=\dfrac{3}{2}\)

Answer 2

a: x=9/14:3/7=9/14x7/3=63/42=3/2

b: x=7/10:7/15=15/10=3/2

Answer 3

a,x=9/14:3/7

x=9/14.7/3

x=3/2

b,x=7/10:7/15

x=7/10.15/7

x=3/2

Answer 4

a.9/14 : X = 3/7

             X = 3/7x9/14

             X=  27/98

b.7/15 x X = 7/10

              X=7/10:7/15

              X=    10/15

              X=  2/5

Answer 5

`a.9/14:x=3/7`

`x=9/14:3/7`

`x=9/14xx7/3`

`x=3/2`

`b.7/15xx x=7/10`

`x=7/10:7/15`

`x=7/10xx15/7`

`x=3/2`

Answer 6

a. 9/14 : X = 3/7

               X= 9/14 : 3/7

               x = 3/2

Answer 7

a) \(\dfrac{9}{14}:x=\dfrac{3}{7}\)

\(x=\dfrac{9}{14}:\dfrac{3}{7}\)

\(x=\dfrac{9}{14}\times\dfrac{7}{3}\)

\(x=\dfrac{3}{2}\)

b) \(\dfrac{7}{15}\times x=\dfrac{7}{10}\)

\(x=\dfrac{7}{10}:\dfrac{7}{15}\)

\(x=\dfrac{7}{10}\times\dfrac{15}{7}\)

\(x=\dfrac{15}{10}\)

\(x=\dfrac{3}{2}\)

Answer 8

a) 9/14 : X = 3/7

              X = 9/14 : 3/7

              X = 3/2

b) 7/15 x X = 7/10

               X = 7/10 : 7/15

               X = 3/2

Answer 9

a)x = 9/14 : 3/7 

   x = ??
