Question

a) X x 3/8 = 31/3 -4 

b) X:5 = 8/7 + 2

Answer 1

a) X x 3/8 = 31/3 -4 

X x 3/8 = 19/3

X= 19/3 : 3/8

X = 152/9

 

b) X:5 = 8/7 + 2

X : 5 = 22/7

X = 22/7 x 5

X = 110/7

Answer 2

a) X x 3/8 = 31/3 - 4 

X x 3/8 = 19/3

X = 19/3 : 3/8

X = 152/9

b) X : 5 = 8/7 + 2

X : 5 = 6

X = 6 x5

X = 30

Answer 3

a) X x 3/8 = 31/3 -4 

    X x 3/8 = 19/3

   X           = 19/3 : 3/8

   X            = 152/9

 

b) X:5 = 8/7 + 2

    X:5  = 22/7

     X   = 22/7 x 5

     X     = 110/7

Answer 4

a) \(x\times\dfrac{3}{8}=\dfrac{31}{3}-4\)

    \(x\times\dfrac{3}{8}=\dfrac{19}{3}\)

    \(x=\)  \(\dfrac{19}{3}:\dfrac{3}{8}\)

    \(x=\dfrac{152}{9}\)

b) \(x:5=\dfrac{8}{7}+2\)

    \(x:5=\dfrac{22}{7}\)

    \(x=\dfrac{22}{7}\times5\)

    \(x=\dfrac{110}{7}\)
