1.	By what number should(- 2/3)^-1be multiplied so that the product becomes(-3/4)^-1?
Answer» Answer: 8/9 Step-by-step EXPLANATION: Let's ASSUME the MISSING number to be y. We know that (-2/3)^-1 * y = (-3/4)^-1. (-2/3)^-1 can be written as -3/2 and (-3/4)^-1 can be written as -4/3. New equation : -3/2 * y = -4/3. Then y = -4/3 / -3/2. (DIVIDING both sides by -3/2). y = -4/3 * -2/3 y = 8/9. Please MARK it as the brainliest.

Answer:

8/9

Step-by-step EXPLANATION: Let's ASSUME the MISSING number to be y.

We know that (-2/3)^-1 * y = (-3/4)^-1.

(-2/3)^-1 can be written as -3/2 and (-3/4)^-1 can be written as -4/3.

New equation : -3/2 * y = -4/3.

Then y = -4/3 / -3/2. (DIVIDING both sides by -3/2).

y = -4/3 * -2/3

y = 8/9.
