there is a pattern with the ratios of corresponding sides. you can see that the measurement of each side of the first triangle divided by two is the measure of the corresponding side of the second triangle. use patterns like this to problem solve the length of missing sides of similar triangles.
8/ (1 1/2) = 36/x....8 muffins to 1 1/2 tsp = 36 ( 3 doz) muffins to x tsp this is a proportion, so we cross multiply (8)(x) = (1 1/2)(36) 8x = 3/2 * 36 8x = 108/2 8x = 54 x = 54/8 x = 6 3/4 <=== 6 3/4 tsps are needed to make 3 doz muffins
