Answer» 1) a:b = 5:7=10:14 and b:c = 14:15 so a :c = 10:15 =2:3 2) a:b = 4:5 = 12:15 and b:c = 12:18 so a:c =( 12/15)*(12/18) = 8:15. 3) x:y = 2:7 = 18:63 and y:z = 9:11 =63:77so x:y:z = 18:63:77 samajh mai nhi aya plese detail

Answer»

1) a:b = 5:7=10:14 and b:c = 14:15 so a :c = 10:15 =2:3

2) a:b = 4:5 = 12:15 and b:c = 12:18 so a:c =( 12/15)*(12/18) = 8:15.

3) x:y = 2:7 = 18:63 and y:z = 9:11 =63:77so x:y:z = 18:63:77

samajh mai nhi aya

plese detail
