Mathematics - Ratios and Proportions - Equivalent ratios - Scale Up the Recipe

'A cookie recipe uses 2 eggs for every 3 cups of flour. If you use 6 cups of flour, how many eggs?' Options: 3, 4, 5, 6. Do 4 scaling scenarios (doubling, tripling recipes). Students intuitively scale by multiplying both parts equally. This IS equivalent ratios without the formal name yet.
