There were approximately 3.79 million births in the United States in 2018. Be sure that in each part you start over using 3.79 million.a) Calculate the number of births per month in the United States. Express this quantity using 2 significant digits and give the implied precision (don’t forget the units).b) Calculate the number of births per day (use 365 days in a year) in the United States. Express this quantity using 3 significant digits and give the implied precision (don’t forget the units).c) Calculate the number of births per hour in the United States. Express this quantity using 1 significant digit and give the implied precision (don’t forget the units).
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
