lab Fraction equality test
Write a program to implement a method that can check whether 2 fractions are equal. You will implement a class called Fraction consisting of a numerator and a denominator. The equality test of 2 fractions should return a boolean value.
Use the following as the tests.
* 1/2, 2/4
* 5/6, 6/7
Hints:
Fraction f1, f2;
f1.equals(f2);

Hints:
Fraction f1, f2;
f1.equals(f2);
lab Fraction Addition
Write a program to implement a method that can do additions of 2 fractions. You will implement a class called Fraction consisting of a numerator and a denominator. The additions of
2 fractions should be equal to a fraction.
Use 1/2+1/3 as the test.
Hints:
Fraction f1, f2;
f1.add(f2);

Homework 10-24-2008
1. Write a program to generate the series 1, 1, 2, 3, 5, 8, 13, ...
The series has a property that the third number is the sum of the first and second numbers. For example, 2=1+1, 3=1+2, and 5=2+3.
2. Write a program to generate the following table of arithmetic expressions
1*1=1 1*2=2 1*3=3 ... 1*9=9
2*1=2 2*2=4 2*3=6 ... 2*9=19
...
9*1=9 9*2=18 9*3=27 ... 9*9=81
