Question

Hear is a diagram showing a mixture of red paint and green paint needed for 1 batch of a particular shade of brown

Answer 1

From the diagram above

mixtures of 3 cups of red paints and 2 cups of green paints for 1 batch

this means for every one batch of brown paint

you have 3 cups of red paints and 2 cups of green paints

for three batches

3 red cups + 3 red cups + 3 red cups = 9 reds cup

2 green cups + 2 green cups + 2 green cups = 6 greens cup

to produce three batches you will need the mixture of 9 red cups of paints and 6 green cups of paint

adding to the diagram you will have 6 more red cups and 4 more green cups
