Hello my dear Colud you please help me in this 2 questions please

Q1/ *Please when you solve use do while loop*

_______________

A fraction is the quotient of two numbers a/b where a and b are both integers and b = 0. a is called the numerator and b the denominator. Here are some operations on fractions: Operation Definition Multiplication a axc X = bd bxd own Example 14 1x4 4 2 25 2x5 10 5 1 4 1.5+4.2 13 + 2 5 2.5 10 2 3 Inverse of is 3 2 a + bd Addition ad + cb bd -= = b Inverse a Inverse of b is a a -a 2 -2 Negation negated is win negated is b b a Division a d =-X- db 1 1 1 2. 2 - 3 2 3 1 3 X b a a 1 1 1.4-1.2 2 1 Subtraction + 1 +1 - 2 b d b 2 4 2.4 8 4 As shown in the examples for multiplication and subtraction, one usually reduces the answer to its simplest form. Thus, 1/2 x 4/5 = 2/5 rather than the 4/10 that results from merely multiplying across. When applying these operations we want to leave the two operands unchanged. For example, given fractions A and B, A B should create a new fraction and not change A or B. Q: Develop an Abstract Data Type for the Fractions.
