Solve Exercise 2 on Page 149 of Mathematics Textbook 3

Problem Statement:

Answer:

Solve Exercise 3 on Page 149 of Mathematics Textbook 3

Problem Statement:

A team of irrigation workers dug 315 meters of canal in 3 days. How many meters of canal can the team dig in 8 days?

Answer:

The number of meters of canal the irrigation team digs in one day is:

315 divided by 3 equals 105 (m)

The number of meters of canal the irrigation team digs in 8 days is:

105 multiplied by 8 equals 840 (m)

Answer: 840 m.

Frequently Asked Questions

What exercises should students complete on page 149 of Mathematics Textbook 3?

Students should complete exercises 1, 2, 3, and 4 on page 149 of Mathematics Textbook 3. These exercises reinforce understanding of numbers up to 100,000, identifying consecutive numbers, and performing basic operations to find unknowns.

How do students solve the problem of finding consecutive numbers in a sequence?

To solve for consecutive numbers in a sequence, students must identify the pattern in the given numbers, as illustrated in exercise 1. For example, filling in blanks such as 3897 to 3902 involves recognizing that each number increases by one.

What is the method for calculating how far a team can dig in 8 days?

To calculate how far a team can dig in 8 days, divide the total meters dug by the number of days worked to find the daily output, then multiply by 8. For instance, 315 meters over 3 days equals 105 meters per day.

Why is understanding area measurement units important in Mathematics?

Understanding area measurement units is crucial because it forms the foundation for solving real-world problems related to space and dimensions. Mastery of these concepts, as discussed in page 150 of Mathematics Textbook 3, helps students apply mathematical reasoning effectively.
