Answer:
(6) Let the number of boys be 7x and that of girls be 5x.
According to the given condition ,
Number of boys = 8 more than Number of girls
=> 7x = 5x + 8
=> 7x-5x=8
=> 2x = 8
=> x= 8/2
=> x=4
Therefore, number of boys = 7 x 4 = 28 and number of girls= 5 x 4 = 20
So, total number of children in the class =
28 + 20 = 48.
(8) Converting into same denominators,
2= 2/1×3/3 =6/3
-1= -1/1×3/3 = -3/3
8 rational numbers between= 5/3,4/3,3/3,2/3,1/3,0/3,-1/3,-2/3
