320 teddy bears dolls to teddy bears=5:8 Dolls=5 Teddy bears=8 x•5 equals 200 200 divided by 5 is 40 x=40 What you do to the top(numerator),you do to the bottom(denominator) 8•40=320 We know there are 5 dolls for every 8 teddy bears.If there is 200 dolls,we have to find how much 5 can go into 200 because we have to find what you have to multiply to make 5 equivalent to 200.200 divided by 5 is 40.We now know we have to multiply 40 by 5 to get 200 so whatever you do to the top you do the bottom.40 times 8 is 320.
