If a is a rational number and b is a rational number, then the product ab must be____.
Solution:
If a is a rational number and b is a rational number, then the product ab must be a rational number.
A Rational Number is a number of the form p/q where p and q are integers and q≠0.
Let's consider an example with two rational numbers, a and b, where
a = 3/5 and b = 4/7
The product of the two numbers will be:
a × b = (3/5) × (4/7) = 12/35 (rational number)
Thus, we can see that the product of two rational numbers is a rational number.
If a is a rational number and b is a rational number, then the product ab must be____.
Summary:
If a is a rational number and b is a rational number, then the product ab must be a rational number.
