Answer 2

Let's break down the expression step by step:

1. (4.5:1/5-5/8:0.75):

   • 4.5:1/5 means the ratio 4.5 to 1/5.
   • 5/8:0.75 means the ratio 5/8 to 0.75.

   To perform arithmetic operations with ratios, we need to convert them to fractions:

   • 4.5:1/5 = (4.5 / 1) / (1/5) = 4.5 * 5 = 22.5
   • 5/8:0.75 = (5/8) / 0.75 = (5/8) * (8/3) = 5/3 ≈ 1.6667

2. 2,3-3 2/3:

   • This seems to be a mix of a comma (,) and a subtraction. It's unclear how to interpret this notation. Are you sure there is no mistake or additional context?

Putting it all together:

22.5 - 1.6667 = 20.8333 (approx.)

Please verify the expression, especially the second part, to ensure that there are no typos or missing elements.
