The product of two rational numbers is –10. If one of the number...
Given Information:
The product of two rational numbers is -10. One of the numbers is 8.
To Find:
The other rational number.
Solution:
Step 1: Identify the given numbers
Let's denote the two rational numbers as x and 8.
Step 2: Formulate the equation
According to the given information, the product of the two numbers is -10. Therefore, we can write the equation as:
x * 8 = -10
Step 3: Solve for x
To find the value of x, we need to isolate it in the equation:
x * 8 = -10
x = -10/8
x = -5/4
Therefore, the other rational number is -5/4, which corresponds to option 'D' in the given choices.
Conclusion:
The other rational number, when one of the numbers is 8 and their product is -10, is -5/4.
