Question

b 8/7:x=3/4

c 4/9+x=8

d 9/5:x=3/4

Answer 1

b: x=8/7:3/4=8/7x4/3=32/21

c: x=8-4/9=72/9-4/9=68/9

d: x=9/5:3/4=9/5x4/3=36/15=2,4

Answer 2

b 8/7:x=3/4

x = 8/7 : 3/4 = 32/21

c 4/9+x=8

x = 8 - 4/9 = 68/9

d 9/5:x=3/4

x = 9/5 : 3/4 = 12/5

Answer 3

b,x=8/7:3/4

x=8/7.4/3

x=32/21

c,x=8-4/9

x=72/9-4/9

x=68/9

d,x=9/5:3/4

x=9/5.4/3

x=12/5

Answer 4

x = 32/21

x = 68/9

x = 12/5

Answer 5

`b)8/7:x=3/4`

`x=8/7:3/4`

`x=8/7xx4/3=32/21`

`c)4/9+x=8`

`x=8-4/9`

`x=72/9-4/9=68/9`

`d)9/5:x=3/4`

`x=9/5:3/4`

`x=9/5xx4/3=12/5`

Answer 6

b) x = 8/7 : 3/4

    x = 32/21

c) x = 8 - 4/9

    x = 63/9

d) x = 9/5 : 3/4

    x = 12/5

Answer 7

b) \(\dfrac{8}{7}:x=\dfrac{3}{4}\)

\(x=\dfrac{8}{7}:\dfrac{3}{4}\)

\(x=\dfrac{32}{21}\)

c) \(\dfrac{4}{9}+x=8\)

\(x=8-\dfrac{4}{9}\)

\(x=\dfrac{68}{9}\)

d) \(\dfrac{9}{5}:x=\dfrac{3}{4}\)

\(x=\dfrac{9}{5}:\dfrac{3}{4}\)

\(x=\dfrac{12}{5}\)

Answer 8

b: x=8/7:3/4=8/7x4/3=32/21

c: x=8-4/9=72/9-4/9=68/9

d: x=9/5:3/4=9/5x4/3=36/15=2,4
