Answer 2

To solve the expression 1 8/17:(12/17 + 2 3/4), you should follow the order of operations, which is typically expressed as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, you need to add the fractions inside the parentheses:

12/17 + 2 3/4

To add 2 3/4 to 12/17, you first need to convert 2 to an equivalent fraction with a common denominator, which is 17. So:

2 = 2 * 17/17 = 34/17

Now, you can add the fractions:

12/17 + 34/17 = (12 + 34)/17 = 46/17

Now, the expression becomes:

1 8/17:(46/17)

Next, divide the whole number by the fraction by inverting the fraction and multiplying:

1 8/17 ÷ (46/17) = (1 8/17) * (17/46)

Now, you can multiply these fractions:

(1 * 17 + 8)/46 = (17 + 8)/46 = 25/46

So, the result of the expression is 25/46.
