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?
original triangle with legs 3, 4 and hypotenuse 5; scaled copy triangle with legs 6, 8 and hypotenuse ?; calculator image

Explanation:

Step1: Analyze the given data

We have the original length 3 and its scaled copy length 6, and original length 4 and its scaled copy length 8.

Step2: Find the scale factor

To find the number (scale factor) we multiply the original length by to get the scaled copy length, we can use the formula: scale factor = $\frac{\text{Scaled Copy Length}}{\text{Original Length}}$.
For the first pair (original = 3, scaled = 6): scale factor = $\frac{6}{3}$ = 2.
For the second pair (original = 4, scaled = 8): scale factor = $\frac{8}{4}$ = 2.
So the scale factor is 2.

Answer:

2
