HOPE MY ANSWER IS CORRECT.

Answer 2

5:15 : : ( consider a variable x in this empty field )54

Multiply 15 with x and 5 with 54

15x = 5 x 54

x = 5 x 54/15

x = 54/3 ( 15 got cancelled with 5 )

x = 18

(b) 11: ( consider a variable x here ) : : 15:90

Now multiply the variable x with 15 and 11 with 90

You get,

15x = 11 x 90
x = 11 x 90/15
x = 11 x 6 ( 90 got cancelled with 15 )
x = 66

(c) 12: ( consider it as x here) :: 72: 54

Multiply 72 with x and 12 with 54

You get,

72x = 12 x 54
x = 12 x 54/ 72
x = 54/6 ( 72 got cancelled with 12 )
x = 9

(d) 1716:7:: ( consider it x here ) : 105

Multiply 7 with x and 1716 with 105

you get,

7x = 1716 x 105
x = 1716 x 105/7
x = 1716 x 15
x = 25740

Hope it helps you
