Question

3/5 : 2/5 + 7/15 x 5/14

8/9 : (X - 3) = 2/7

Answer 1

`3/5 : 2/5 + 7/15 x 5/14`

` = 3/5 xx 5/2 + 7/15 xx 5/14`

`= 3/2  + 1/6`

` = 9/6 + 1/6`

` = 10/6`

`= 5/3`

 

` 8/9 : ( x - 3) = 2/7`

` x - 3 = 8/9 : 2/7`

` x - 3 = 8/9 xx 7/2`

` x - 3 = 28/9`

` x = 28/9 + 3`

` x = 55/9`

Answer 2

A. \(\dfrac{17}{75}\)

Answer 4

=3/5 x 5/2+7/15 x 5/14

=1\(\dfrac{1}{2}\)+\(\dfrac{1}{6}\)

=\(1\dfrac{2}{3}\)

x-3=8/9 x 7/2

x-3=3\(\dfrac{1}{9}\)

x=6\(\dfrac{1}{9}\)
