1. Solve exercise 1 on page 87 of Math textbook for 4th grade
Problem:
Compute the following:
a) 708 ÷ 354
b) 704 ÷ 234
7552 ÷ 236
8770 ÷ 365
9060 ÷ 453
6260 ÷ 156
Solution method:
Refer to detailed instructions on how to perform division of numbers with multiple digits by three-digit numbers in Exercise 1 on page 86 of Math textbook for 4th grade.
2. Solve exercise 2 on page 87 of Math textbook for 4th grade
Problem:
People pack candies into 24 boxes, with each box containing 120 candies. How many boxes are needed to pack all the candies if each box contains 160 candies?
Solution method:
- Calculate the total number of candies by multiplying the number of boxes by the number of candies per box.
- To determine the number of boxes needed if each box contains 160 candies, divide the total number of candies by 160 (candies/box).
Answer:
The total number of candies is:
120 x 24 = 2880 (candies)
If each box contains 160 candies, then the number of candy boxes needed is:
2880 : 160 = 18 (boxes)
Answer: 18 boxes.
3. Solve exercise 3 on page 87 of Math textbook for 4th grade
Problem:
Calculate in two ways:
a) 2205 : (35 x 7)
b) 3332 : (4 x 49)
Solution method:
- Method 1: Perform the calculation inside the parentheses first, then outside the parentheses.
- Method 2: Apply the formula: a : (b x c) = a : b : c, then perform the calculation from left to right.
Answer:
a) 2205 : (35 x 7) = ?
Method 1: 2205 : (35 x 7) = 2205 : 245 = 9
Method 2: 2205 : (35 x 7) = 2205 : 35 : 7 = 63 : 7 = 9
b) 3332 : (4 x 49) = ?
Method 1: 3332 : (4 x 49) = 3332 : 196 = 17
Method 2: 3332 : (4 x 49) = 3332 : 4 : 49 = 833 : 49 = 17
