Homework Helper

Is 1 liter or 1 milliliter a more reasonable estimate for a drop of food coloring Brianne will use to color icing for baking?

Use a liter to measure greater capacity.

Use a milliliter to measure lesser capacity.

A drop of food coloring is a small amount. It is unreasonable to estimate that one drop is a liter of liquid.

So, 1 milliliter of food coloring is a more reasonable estimate.

Yes; Sample answer: 3 liters is a reasonable amount for a watering

can to hold.

It is reasonable to say she is heating 300 milliliters because

3 milliliters is only about one spoonful.

It will probably take a lot of paint to cover four walls. So, it is more

reasonable to measure the paint he will need in liters.
