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 by which we multiply each original length to get the length in the scaled copy, we can use the ratio of corresponding sides. Let's take the second - row values: the original side is 3 and the scaled - copy side is 6. The ratio is $\frac{6}{3}=2$. We can check with the third - row values: the original side is 4 and the scaled - copy side is 8, and $\frac{8}{4}=2$.
