-6 divide n = -9 and 5 over 6
What numbers have no recrpricol?
The product of -7 over 12 and a mystery number is -1 over 2. What is the number?
Can anyone help mee?
Zero has no reciprocal. The reciprocal of 1 is 1. The reciprocal of -1 is -1.
If -7x/12 = -1/2, then
-12 = -14x
x = 6/7
I did the first one in a different post
To solve the expression (-6/n) = (-9 + 5/6), we can follow these steps:
Step 1: Get a common denominator for the fractions on the right side of the equation.
- The denominator on the right side is 6, so we can rewrite -9 as (-54/6) to have a common denominator.
Step 2: Combine the fractions on the right side by adding their numerators.
- (-54/6) + (5/6) = (-54 + 5) / 6
- (-54 + 5) = -49, so the equation becomes: -49/6
Step 3: Now we can set up an equation by equating the fractions on both sides.
- (-6/n) = -49/6
Step 4: To isolate the variable 'n', we can cross-multiply: (-6) * 6 = (-49) * n.
- -36 = -49n
Step 5: Solve for 'n' by dividing both sides of the equation by -49.
- -36 / -49 = (-49n) / -49
- (36/49) = n
Therefore, the solution to the equation (-6/n) = (-9 + 5/6) is n = 36/49.
