Question

a) x : 5/13 + 2/26 = 1

b) x × 3/5 = 7/8

c) x = 3/7 + 4/21 + 5/42

Answer 1

a. 60/169

b. 35/24

c.32/42

Answer 2

a) \(x:\frac{5}{13}+\frac{2}{26}=1\)

                \(x:\frac{5}{13}=1-\frac{2}{26}\)

                \(x:\frac{5}{13}=\frac{12}{13}\)

                        \(x=\frac{12}{13}\times\frac{5}{13}\)

                        \(x=\frac{60}{169}\)

b)   \(x\times\frac{3}{5}=\frac{7}{8}\)

                 \(x=\frac{7}{8}:\frac{3}{5}\)

                 \(x=\frac{35}{24}\)

c)  \(x=\frac{3}{7}+\frac{4}{21}+\frac{5}{42}\)

     \(x=\frac{3\times6}{7\times6}+\frac{4\times2}{21\times2}+\frac{5}{42}\)

    \(x=\frac{18}{42}+\frac{8}{42}+\frac{5}{42}=\frac{31}{42}\)

Answer 3

x:5/13+2/26=1

x:5/13=1-2/26

x:5/13=12/13

x         =12/13x5/13

x          =60/169

x.3/5=7/8

x       =7/8:3/5

x        =35/24

x=3/7+4/21+5/42

x=13/21+5/42

x=31/42+5/42

x=31/42
