вроде так

Answer 2

Let's break down the given expression step by step:

1. 10 - 1 = 9

2. 3/4 * (2 1/3 + 1 2/5): First, let's add the mixed numbers inside the parentheses:

   • 2 1/3 = 2 + 1/3 = 7/3
   • 1 2/5 = 1 + 2/5 = 7/5

   Then, sum these two fractions:

   • 7/3 + 7/5 = (35/15) + (21/15) = 56/15

   Now, multiply the result by 3/4:

   • 3/4 * 56/15 = (3 * 56) / (4 * 15) = 168/60 = 14/5

3. 1 5/9 = 1 + 5/9 = 14/9

Now, let's put it all together and solve for the final result:

9 + (14/5) / (14/9)

When you divide fractions, you can multiply by the reciprocal of the second fraction:

9 + (14/5) * (9/14)

The 14 in the numerator and denominator cancel out:

9 + 1

So, the final result is 10.
