Guidelines for Solving Exercise 1 on Page 58 of Mathematics 5 Textbook
Problem:
Mental Calculation:
Multiplying numbers:
Calculating products: 1.48 x 10, 5.12 x 100, 2.571 x 1000
To achieve products 80.5, 805, 8050, 80500, what should 8.05 be multiplied by?
Solution Method:
Refer to the guide on multiplying a decimal by 10, 100, 1000,... in solving Exercise 1 on page 57 of Mathematics 5 Textbook.
The Answers:
a) 1.48 x 10 = 14.8, 5.12 x 100 = 512
2.571 x 1000 = 2571, 15.5 x 10 = 155
0.9 x 100 = 90, 0.1 x 1000 = 100
b) 8.05 x 10 = 80.5, 8.05 x 100 = 805
8.05 x 1000 = 8050, 8.05 x 10000 = 80500
