1. Solving Exercise 1 - Math 5 Page 119
Problem:
a) Read the measurements:
5m3; 2010cm3; 2005dm3; 10,125m3; 0,109dm3;
0,015dm3; 1/4m3; 95/100dm3
b) Write the volume measurements:
One thousand nine hundred fifty-two cubic centimeters;
Two thousand ten cubic meters;
Three-eighths cubic decimeters;
Zero point nine one nine cubic meters.
Solution Method:
Refer back to the instructions on how to read/write volume measurements in the Exercise 1 solution on pages 116, 117 of Math 5 textbook.
Answer:
5m3: Five cubic meters.
2010cm3: Two thousand ten cubic centimeters.
2005dm3: Two thousand five cubic decimeters.
10,125m3: Ten point one two five cubic meters.
0,109dm3: Zero point one zero nine cubic decimeters.
1/4m3: One-quarter cubic meters.
95/100dm3: Ninety-five hundredths cubic decimeters.
b) One thousand nine hundred fifty-two cubic centimeters is written as: 1952cm3.
Two thousand ten cubic meters is written as: 2015m3.
Three-eighths cubic decimeters is written as: 3/8 dm3.
Zero point nine one nine cubic meters is written as: 0,919m3.
2. Solving Exercise 2 - Solving Math Class 5 Practice Problems on Page 119
Problem:
Correct is marked with C, incorrect is marked with I:
0.25m3 is:
a) Not point twenty-five cubic meters.
b) Not point two hundred fifty cubic meters.
c) Twenty-five percent cubic meters.
d) Twenty-five thousandth cubic meters.
Solution Method:
- Reading decimal numbers: When reading a decimal number, we read from highest place value to lowest: Read the whole part, then read the decimal point, and finally read the decimal part.
- Reading m3 symbol: Cubic meters.
Answer:
a) C
b) C
c) C
d) I
