I think the The answer 1/1 or1/2! If it is not correct then ask some one else
Rate is closer to a constant pattern , example: I'm walking at a rate of 2 miles an hour.
Ratio is related to the proportion of two or more objects, example: The ratio for a perfect tang juice is 1 packet of tang dust thingy for 1.5 liters of water.
Hope it helps :)

Tbh i dont really remember how to this this but the only way i could think of solving it is saying how a spuare/rectangle have all equal sides so if they have all equal sides you can divide that number by 4 so 4/30=7.5 so i would say x = 7.5 tell me if its wrong
