Question

Answer 1

a,x=4.3/4

x=3

b,x=9/15:3/2

x=2/5

Answer 2

a) \(x=4x\dfrac{3}{4}\)

\(x=3\)

 

b) \(x=\dfrac{9}{15}:\dfrac{3}{2}\)

\(x=\dfrac{2}{5}\)

Answer 3

`a)`

`x :3/4=4`

`x=4xx3/4`

`x=3`

_________________

`b)`

`x xx3/2=9/15`

`x=9/15:3/2`

`x=9/15xx2/3`

`x=[3xx3xx2]/[3xx5xx3]`

`x=2/5`

Answer 4

\(a,x=4\times\dfrac{3}{4}\)

x = 3

\(b,x=\dfrac{9}{15}:\dfrac{3}{2}\)

\(x=\dfrac{9}{15}\times\dfrac{2}{3}\)

\(x=\dfrac{6}{15}=\dfrac{2}{5}\)

Answer 5

a)\(x=4\times\dfrac{3}{4}=3\)

\(b,x=\dfrac{9}{15}:\dfrac{3}{2}=\dfrac{9}{15}\times\dfrac{2}{3}=\dfrac{2}{5}\)
