Question

By what rational number should we multiply - 5/9 to get 1/5?
​

Answer 1

Answer:

-5/9 by -9/25 to get 1/5.

Explanation:

Certainly! To solve the problem, we need to find the rational number that, when multiplied by -5/9, gives 1/5 as the result.

Let's call this unknown rational number "x". So, we have:

-5/9 * x = 1/5

We want to solve for "x" by isolating it on one side of the equation. To do this, we can start by multiplying both sides of the equation by the reciprocal of -5/9, which is -9/5. This gives us:

x = (1/5) * (-9/5)

Now we can simplify the right-hand side of the equation:

x = -9/25

Therefore, we should multiply -5/9 by -9/25 to get 1/5.
