So if there are 60 clownfish and the ratio from clownfish to angelfish is 5:4, this is the equation you are looking at: 5:4 = 60:? To find ? you have to do 60 divided by 5 which equals 12 and multiply it times 4 to see how many angelfish there will be if there are 60 clownfish. 12 x 4 = 48 So if there are 60 clownfish there will be 48 angelfish. The ratio is 60:48
For the next one, same thing if there are 48 angelfish, then you are looking at this equation: 4:3 = 48:? Again, we solve like we did the last one. 48 divided by 4= 12 3 x 12= 36 So, if there are 48 angelfish there will be 36 goldfish. The ratio is 48:36 I hope this helps:)
you can basically guess and check with this question but I knew if it was a rectangle then 2 sides would be larger than the other. So I started off figuring out what times what equals 8 and I got 2 and 4. So I put those in for the side lengths and I got 12.
