Revision of Whole Numbers
Example:
325,614
Expanded form:
300,000 + 20,000 + 5,000 + 600 + 10 + 4
Revision of Comparing Numbers
45,000 > 42,500
18,200 < 20,000
Revision of Roman Numerals
- V = 5
- X = 10
- L = 50
- C = 100
- IX = 9
- XL = 40
Revision of Fractions
1/2 = 2/4
3/5 is a proper fraction.
7/4 is an improper fraction.
7/4 = 1 3/4
Revision of Decimals
5/10 = 0.5
25/100 = 0.25
Revision of Addition and Subtraction
2,450 + 1,250 = 3,700
5,000 – 2,350 = 2,650
Fractions:
2/5 + 1/5 = 3/5
Decimals:
2.5 + 1.2 = 3.7
