Question

original scaled copy 5 ? 3 6 4 8 what number can you multiply each original length by to get each length in the scaled copy?

Explanation:

Step1: Find the scale - factor

To find the number to multiply the original lengths by to get the scaled - copy lengths, we can use the ratio of corresponding sides. Let's take one pair of corresponding sides, say the side of length 3 in the original and 6 in the scaled copy. The ratio is $\frac{6}{3}=2$. We can check with another pair, like the side of length 4 in the original and 8 in the scaled copy. $\frac{8}{4}=2$.
