9. 5 -- *. --- 10. 6

It looks like you're trying to perform multiplication with fractions. Here is how you would calculate it:

You have two fractions: 9/10 and 5/6. To multiply them, you simply multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together.

(9/10) * (5/6) = (9 * 5) / (10 * 6)

Perform the multiplication:

45 / 60

Now, the result is a fraction which can be simplified by finding the greatest common divisor (GCD) for 45 and 60. In this case, the GCD is 15.

So, divide both the numerator and the denominator by 15:

(45 ÷ 15) / (60 ÷ 15) = 3 / 4

The simplified result of multiplying 9/10 by 5/6 is 3/4.
