Lesson 5 performing More Than One Operation 61

performing More Than One Operation

Engage

To raise awareness for clean air and to promote biking as a mode of transportation, bikers held the Tour of the Fireflies event.

At the start of the biking event, 200 bottles of water were at the water station. After 173 riders have each gotten a bottle, the organizers brought out 48 more bottles of water. How many bottles of water were at the water station by that time?

Let’s Build Your Understanding

To solve the problem, we first subtract 173 from 200.200 – 173 = 27

Then add 48 to the difference.27 + 48 = 75

Thus, there were 75 bottles of water at the water station at that time.

If we want to write this in one number sentence, then we have

200 – 173 + 48 = 75For number sentences involving addition and subtrac-

tion only, we do the operations from left to right.

Lesson 3 What Are Some Ways of Separating the Components of Mixtures? 17

What Are Some Ways of Separating the Components of Mixtures?

Separating mixtures occur in different areas of science. In chemistry, water softeners are used in order to separate the ions that give hardness to water. In engineering, oil and gas filters are used in order for the machines to function fully and prevent malfunctioning.

In the life science, the kidney is the organ that filters wastes so that the body will excrete these wastes. Can you think of other areas of science where separating mixtures occur?

The photo above shows some of the by-products of coconut fruit—the milk and the oil. These by-products are derived from the coconut fruit through the different techniques used in separating mixtures.

The separation of a mixture into its component substances uses the differences in the physical properties of the materials in the mixtures. Can you think of the different ways of separating mixtures in your homes?
