Answer:

for eg;
3/5 is proportional to 15/25
I'm gonna do number 8 but do the SAME steps for the rest.....take the denominator multiply it by the whole number then add that answer to the numerator so now it will be 23/5×15/4 ... once u have that just multiply across but DON'T CROSS MULTIPLY multiply straight across and u'll get ur answer... answer to 8 is 345/20 now divide that answer like this.. 345÷20= 17.25
I believe the answer is 19 cm, because you compare 8cm to the other side, it's basically the same. Multiply 2 x 8 and you get 19 cm.
