a) 21718 x 4 b) 18061 x 5
12198 x 4 10670 x 6
Answer:
Solve exercise 2 on page 162 of Math 3 textbook
Problem Statement:
A storage tank contains 63150 liters of oil. Oil has been withdrawn from the tank three times, each time withdrawing 10715 liters. Find the remaining amount of oil in the tank.
Answer:
Amount of oil transferred out of the storage:
10715 x 3 = 32,145 (liters)
Remaining oil in the storage:
63,150 - 32,145 = 31,005 (liters)
Answer: 31,005 liters
Solve exercise 3 on page 162 of Math 3 textbook
Problem Statement:
Evaluate the value of the expression:
a) Calculate 10303 x 4 + 27854 b) 26742 + 14031 x 5
21507 x 3 - 18799 81025 - 12071 x 6
Answer:
a) 10303 x 4 + 27854 = 41,212 + 27,854 = 69,066
21507 x 3 - 18799 = 64,521 - 18,799 = 45,722
b) 26742 + 14031 x 5 = 26,742 + 70,155 = 96,897
81025 - 12071 x 6 = 81,025 - 72,426 = 8,599
Solve exercise 4 on page 162 of Math 3 textbook
Problem Statement:
Mental Calculation:
Solution Approach:
11000 x 3 = ?
Mentally calculate 11 thousand x 3 = 33 thousand
So, 11000 x 3 = 33,000
a) 3000 x 2 b) 11000 x 2 =
2000 x 3 = 6000 12000 x 2 = 24000
4000 x 2 = 8000 13000 x 3 = 39000
5000 x 2 = 10000 15000 x 2 = 30000
Answer:
Students mentally calculate and record the results as follows:
a) 3000 x 2 = 6000 b) 11000 x 2 = 22000
2000 x 3 = 6000 12000 x 2 = 24000
4000 x 2 = 8000 13000 x 3 = 39000
5000 x 2 = 10000 15000 x 2 = 30000
