1. Solve question 1 - 5th Grade Math Page 151 Textbook
Solution Method:
a) Apply the conversion method: 1/10; 1/100; 1/1000,... to the form of fractions.
b) Multiply both the numerator and denominator of the fraction by a natural number to make the fraction in the form of 10; 100; 1000,...
2. Solve question 2 - 5th Grade Math Reviewing Decimal Numbers (Continued) Page 151
Problem:
a) Write the decimal numbers in the form of a percentage:
0.35 = ....; 0.5 = ...; 8.75 = ....
b) Write the percentage in the form of a decimal number:
45% = ...; 5% = ....; 625% = .....
Solution Method:
Students apply the following formula: 1/100 = 0.01 = 1%.
Answer:
a) 0.35 = 35%; 0.5 = 0.50 = 50%; 8.75 = 875%
b) 45% = 0.45; 5% = 0.05; 625% = 6.25
3. Solve question 3 - 5th Grade Math Book Page 151
Solution Method:
- Step 1: Convert the given fractions in the problem to decimal fractions.
- Step 2: Convert the decimal fraction found into a decimal number by dividing the numerator by the denominator of the fraction.
4. Solve question 4 - 5th Grade Math Page 151
Problem:
Write the following numbers in ascending order:
a) 4.5; 4.23; 4.505; 4.203.
b) 72.1; 69.8; 71.2; 69.78.
Solution Method:
To compare two decimal numbers, we can:
- Compare the integer parts as if comparing two natural numbers. The decimal number with the larger integer part is considered larger.
- If the integer parts are equal, compare the decimal parts, digit by digit, from the tenths place, hundredths place, thousandths place, and so on. The decimal number with the larger digit in the corresponding place is considered larger.
Answer:
a) The decimal numbers in ascending order are: 4.203; 4.23; 4.5; 4.505.
b) The decimal numbers in ascending order are: 69.78; 69.8; 71.2; 72.1.
5. Solve question 5 - 5th Grade Math Book Page 151
