1. A rational number is a number that can be written as a fraction.
For example: 1/3, 5/7, 90/666, etc
Note: Any integer can be written as a fraction.
Look:
5 = 5/1 = rational
-14 = -14/1 = rational
2. There is no difference between a rational and integer.
16.) 38.25= 4.25h
divide by 4.25 on both sides
h=9
17.)214= 1/3x
divide by 1/3 on both sides
x= 642
18.)70= 2x
divide by 2 on both sides
x=35
19.)18.69= 5.25+1.68x
subtract 5.25 on both sides
13.44=1.68x
divide by 1.68 on both sides
x=8
