The answer is 5/2 in fraction form or 2.5 in decimal form.
1.4 meters is equal to 140 centimeters. We can find the ratio with just these two side lengths because we know that the shapes are similar, so the other corresponding sides will also have the same ratio.
Then, we can take 140 and divide it by 56 which, simplified, gives us the fraction 5/2. Because of the Fundamental Theorem of Similarity, you keep the fraction the way it is. (If you are finding the ratio of areas or surface areas, you square the fraction, and if you are finding the ratio of the volumes you cube it.)
I hope this helped, if you are confused or this didn’t help, feel free to ask questions!
