Question

\(a,\)\(\dfrac{5}{7}+\dfrac{6}{9}\)

\(b,\dfrac{1}{6}-\dfrac{5}{8}\)

\(c,\dfrac{7}{4}\times\dfrac{2}{6}\)

\(d,\dfrac{6}{9}\div\dfrac{4}{8}\)

Answer 1

a: =45/63+42/63=87/63=29/21

b: =4/24-15/24=-11/24

c: =14/24=7/12

d: \(=\dfrac{2}{3}\cdot2=\dfrac{4}{3}\)

Answer 2

`a) 5/7 + 6/9= 45/63 + 42/63=87/63=29/21`

`b) 1/6 - 5/8= 8/48- 30/48= -22/48=-11/24`

`c) 7/4 xx 2/6= 14/24=7/12`

`d) 6/9 : 4/8=6/9 xx 8/4= 48/36=4/3`
