Write an explanation in words to Eli about how He can use his table to find how many liters of blue paint and how many liters of yellow paint will he need o make 45 liters of green paint

Answer 1

The ratio between the amount of blue and yellow paint needed to make green paint is 2: 3.

That is, for every 2 liters of blue paint you need 3 liters of yellow paint.

In the same way, for every 4 liters of blue paint, 6 liters of yellow paint are needed.

Then, to continue filling the table, you must consecutively sum 2 liters of blue paint and 3 liters of yellow paint in the corresponding column. This will increase the amount of green paint by a factor of 5 liters.

The same procedure is followed until 45 liters are summed to the green paint column. Then, the data in that row will indicate how much blue and yellow paint is needed:

18 liters of blue paint

27 liters of yellow paint

To verify the result divided 18/27

The result should be 0.6667 = 2/3, which is the ratio sought
