Solve:
a) 67494 : 7 b) 359361 : 9
42789 : 5 238057 : 8

Solution:
Review the method of setting up division problems for dividing numbers with multiple digits by a single-digit number in Solution for question 1 on page 77 of Grade 4 Math textbook.

2. Solve question 2 on page 78 of Grade 4 Math textbook

Find two numbers knowing their sum and difference:
a) 42506 and 18472
b) 137895 and 85287

To find two numbers given their sum and difference:
- The larger number is half the sum plus half the difference
- The smaller number is half the sum minus half the difference

a) The smaller number is: 12017
The larger number is: 30489
b) The smaller number is: 26304
The larger number is: 111591

3. Solution to problem 3 page 78 Mathematics Grade 4 textbook

A train has 3 carriages, each carrying 14580 kg of goods, and 6 other carriages, each carrying 13275 kg of goods. What is the average weight of goods carried per carriage?

Step 1: Find the total number of carriages by adding the number of carriages carrying 14580 kg of goods and the number of carriages carrying 13275 kg of goods.
Step 2: Calculate the total weight of goods carried by adding the weight of goods carried by the 3 carriages and the weight of goods carried by the 6 carriages.
Step 3: Calculate the average weight of goods carried per carriage by dividing the total weight of goods carried by the total number of carriages.

Total number of carriages: 3 + 6 = 9 carriages
Total goods carried: (14580 x 3) + (13275 x 6) = 123390 kg
Average goods per carriage: 123390 / 9 = 13710 kg
Answer: 13710 kg

4. Solution to problem 4 page 78 Mathematics Grade 4 textbook

Calculate in two ways:
a. (33164 + 28528) : 4 = 15423
(33164 + 28528) : 4 = 15423

Method 1: Perform the operation inside the parentheses first, then outside the parentheses.
Method 2: Apply the formula: (a + b) : c = a : c + b : c or (a - b) : c = a : c - b : c

a. (33164 + 28528) : 4 = 15423
(33164 + 28528) : 4 = 15423

b. (403494 - 16415) : 7 = 55297
(403494 - 16415) : 7 = 55297

Frequently Asked Questions

What resources are available for solving Grade 4 Math exercises?

The solutions for exercises on page 78 of the Grade 4 Math textbook offer detailed guidance to help students review and reinforce their knowledge. These resources are designed to improve problem-solving skills effectively and make math learning easier.

How do you solve question 1 from the Grade 4 Math textbook?

To solve question 1, set up the division problems for each part. For part a, divide 67494 by 7. For part b, divide the numbers 359361 and 942789 by 5, and then 238057 by 8. Review the methods in the previous sections for assistance.

What are the methods for finding two numbers given their sum and difference?

To find two numbers based on their sum and difference, the larger number can be calculated as half the sum plus half the difference, while the smaller number is half the sum minus half the difference. This formula provides an effective solution.

How is the average weight of goods per carriage calculated in problem 3?

To calculate the average weight of goods per carriage, first determine the total number of carriages. Then, calculate the total weight of goods and divide this total by the number of carriages. This method provides an accurate average weight.

What are the two methods for calculating the expression in problem 4?

In problem 4, you can calculate the expression by performing operations inside the parentheses first and then outside, or by applying the formula for distributing division across addition or subtraction. Both methods yield the same result.
