Question

Answer 1

a)

X = 3/4 :7

X = 3/28

b)

2:x = 2/5+1/3

2:x = 11/15

x = 2: 11/15

x = 30/11

Answer 2

a.Xx7=3/4

        X=3/4:7

          X=3/28

b.2:X-1/3=2/5

         2:X=2/5+1/3

         2:X=11/15

             X=2:11/15

             X=30/11

Answer 3

a/3/28

b/30/11

Answer 4

a)x=3/4:7

x=3/28

b)x-1/3=2/5:2

x-1/3=1/5

x=1/5+1/3

x=3/15+5/15

x=8/15

Answer 5

a)X = 3/4 :7

X = 3/28

b)2:x = 2/5+1/3

2:x = 11/15

   x = 2: 11/15

  x = 30/11

Answer 6

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

\(x=\dfrac{3}{4}:\dfrac{7}{1}\)

\(x=\dfrac{3}{4}\times\dfrac{1}{7}\)

\(x=\dfrac{3}{28}\)

b)\(x-\dfrac{1}{3}=2:\dfrac{2}{5}\)

\(x-\dfrac{1}{3}=\dfrac{2}{1}:\dfrac{2}{5}\)

\(x-\dfrac{1}{3}=\dfrac{2}{1}\times\dfrac{5}{2}\)

\(x-\dfrac{1}{3}=\dfrac{10}{2}\)

\(x-\dfrac{1}{3}=5\)

\(x=\dfrac{1}{3}+5\)

\(x=\dfrac{1}{3}+\dfrac{5}{1}\)

\(x=\dfrac{16}{3}\)

Answer 7

a) X x 7 = 3/4

    X       = 3/4 : 7

    X       = 3/18

b) 2 : X - 1/3 = 2/5

    2 : X          = 2/5 +1/3

    2 : X          = 11/15

         X          = 2 : 11/15

         X          = 30/11
