Question

a)5/10+3/5         b)3/2+5/4

c)5/2-3/8            d)x:3/4=1/7

e)X x3/2=1/8

Answer 1

a,=5/10+6/10

=11/10

b,=6/4+5/4

=11/4

c,=20/8-3/8

=17/8

d,x=1/7.3/4

x=3/28

e,x=1/8:3/2

x=1/8.2/3

x=1/12

Answer 2

a) \(\dfrac{5}{10}+\dfrac{3}{5}=\dfrac{5}{10}+\dfrac{6}{10}=\dfrac{11}{10}\)

 

b) \(\dfrac{3}{2}+\dfrac{5}{4}=\dfrac{6}{4}+\dfrac{5}{4}=\dfrac{11}{4}\)

 

c) \(\dfrac{5}{2}-\dfrac{3}{8}=\dfrac{20}{8}-\dfrac{3}{8}=\dfrac{17}{8}\)

 

d) \(x:\dfrac{3}{4}=\dfrac{1}{7}\)

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

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

 

e) \(X\times\dfrac{3}{2}=\dfrac{1}{8}\)

\(X=\dfrac{1}{8}:\dfrac{3}{2}\)

\(X=\dfrac{1}{8}\times\dfrac{2}{3}\)

\(X=\dfrac{1}{12}\)

Answer 3

a). \(\dfrac{5}{10}+\dfrac{3}{5}\)    

\(=\dfrac{5}{10}+\dfrac{6}{10}\)

\(=\dfrac{11}{10}\)

b).\(\dfrac{3}{2}+\dfrac{5}{4}\)

\(=\dfrac{6}{4}+\dfrac{5}{4}\)

\(=\dfrac{11}{4}\)

c).\(\dfrac{5}{2}-\dfrac{3}{8}\)

\(=\dfrac{20}{8}-\dfrac{3}{8}\)

\(=\dfrac{17}{8}\)

d). \(x:\dfrac{3}{4}=\dfrac{1}{7}\)

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

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

e). \(x.\dfrac{3}{2}=\dfrac{1}{8}\)

\(x=\dfrac{1}{8}:\dfrac{3}{2}\)

\(x=\dfrac{1}{8}.\dfrac{2}{3}\)

\(x=\dfrac{2}{24}=\dfrac{1}{12}\)

Answer 4

a) \(\dfrac{5}{10}+\dfrac{3}{5}=\dfrac{5}{10}+\dfrac{6}{10}=\dfrac{11}{10}\)

b) \(\dfrac{3}{2}+\dfrac{5}{4}=\dfrac{6}{4}+\dfrac{5}{4}=\dfrac{11}{4}\)

c) \(\dfrac{5}{2}-\dfrac{3}{8}=\dfrac{20}{8}-\dfrac{3}{8}=\dfrac{17}{8}\)

d) \(X:\dfrac{3}{4}=\dfrac{1}{7} \\ X=\dfrac{1}{7}x\dfrac{3}{4}\\ X=\dfrac{3}{28}\)

e) \(Xx\dfrac{3}{2}=\dfrac{1}{8}\\X=\dfrac{1}{8}:\dfrac{3}{2}\\ X=\dfrac{1}{12} \)
