Answer 2

It seems like you've provided a series of arithmetic expressions. Let's break down each one:

1. $\frac{3}{4} : \frac{5}{6} + 2$

First, let's perform the division and then the addition:

$\frac{3}{4} : \frac{5}{6} + 2 = \frac{3}{4} \times \frac{6}{5} + 2 = \frac{18}{20} + 2 = \frac{9}{10} + 2 = \frac{29}{10}$

2. $\frac{1}{2} \times \frac{2}{3} - 1$

Here we'll perform the multiplication and then the subtraction:

$\frac{1}{2} \times \frac{2}{3} - 1 = \frac{1}{3} - 1 = -\frac{2}{3}$

3. $1 : \frac{1}{9}$

Division of a whole number by a fraction is the same as multiplying the whole number by the reciprocal of the fraction:

$1 : \frac{1}{9} = 1 \times \frac{9}{1} = 9$

Putting it all together:

$\frac{29}{10}$, $-\frac{2}{3}$, and $9$

These are the results of the given arithmetic expressions.
