Question

x nhân 7 = 9 phần 10

Answer 1

`x xx 7 = 9 / 10`

`x = 9 / 10 : 7`

`x = 9 / 10 xx 1 / 7`

`x = 9 / 70`

Answer 2

\(x\times7=\dfrac{9}{10}\)

\(x=\dfrac{9}{10}:7\)

\(x=\dfrac{9}{10}:\dfrac{7}{1}\)

\(x=\dfrac{9}{10}\times\dfrac{1}{7}\)

\(x=\dfrac{9}{70}\)

Answer 3

x = 9/10 : 7

x = 70/9

Answer 4

\(x\times7=\dfrac{9}{10}\)

\(x=\dfrac{9}{10}:7\)

\(x=\dfrac{9}{70}\)

Answer 5

x=\(\dfrac{70}{9}\)

Answer 6

X x 7 = 9/10

X       = 9/10 : 7

x        =  9/70

Answer 7

x=\(\dfrac{9}{10}:7=\dfrac{9}{10x7}\)

x=\(\dfrac{9}{70}\)
