Pattern B consists of four tiles like pattern A. Write a proportion involving red dots and blue dots in pattern A and B. Are they in direct proportion? If yes, write the constant of proportion.
The number of red dots in pattern A (•) = 4
The number of blue dots in pattern A (⃘) = 2
Pattern B consists of four tiles like pattern A i.e.
Patter A × 4 = Pattern B
∴ Proportion in pattern =
Now, proportion of blue dots and red dots in pattern B =
