To determine which blocks have proportional length-to-width ratios, we need to calculate the ratio of length to width for each block:
-
Block A: Length = 23, Width = 115
Ratio = Length / Width = 23 / 115 = 1 / 5 -
Block B: Length = 46, Width = 230
Ratio = Length / Width = 46 / 230 = 1 / 5 -
Block C: Length = 460, Width = 52
Ratio = Length / Width = 460 / 52 = 115 / 13 (approximately 8.85)
Now we compare the ratios:
- Block A has a ratio of 1/5.
- Block B has a ratio of 1/5.
- Block C has a different ratio (not 1/5).
So, Block A and Block B have the same ratio of length to width, while Block C does not.
Thus, the answer is Block A and Block B.
