kulang yata given mo..
pero kung yan lng eto solution..
x=ky
28=k35
so para k nlng ang matira sa right side..
28/35=k35/35
so na cancel out na ung 35 and k nlng tira..
28/35=k
28 divided by 35 is equal to 0.8, so the ans. is 0.8
0.8=k
k=0.8
x = ky

when x = 28;  y=35;  k=?

28 = k (35)

28 = k (35)
35        35

k = [tex] \frac{28}{35} [/tex]  or  [tex] \frac{4}{5} [/tex]
