Answer:
1 batch of sky blue paint:
- blue paint = 2 cups
- white paint = 1 gallon
Clare can make 2 batches of sky blue paint by multiplying the components by 2:
2 batches of sky blue paint:
- blue paint = 2 × 2 = 4 cups
- white paint = 1 × 2 = 2 gallons
So she will need 4 cups of blue paint and 2 gallons of white paint to make 2 batches of sky blue paint.
To make a mixture that is a darker shade of blue, increase the proportion of blue paint and reduce the proportion of white paint.
To make a mixture that is a lighter shade of blue, increase the proportion of white paint and reduce the proportion of blue paint.
